Issues resolved in 10.7.0 through 10.7.0 February 2020 Update

Critical:

Reference Number	Related Article	Found in ENS Version	Resolved in ENS Version	Issue Description
1228079	KB90301	10.5.3	10.7.0 10.6.1 10.5.5	Issue: A blue screen error or hang might occur when you install or upgrade a McAfee product with SysCore, and ENS Exploit Prevention is enabled, or Host IPS Exploit Prevention is enabled. The issue is timing-related and does not always occur. Resolution: This issue is resolved in ENS 10.5.5 and ENS 10.6.1, and is resolved in ENS 10.7.0. A utility, mfeepmpk_utility.exe, is included in the ENS 10.5.5 and ENS 10.6.1 installation packages to resolve the issue with the faulty driver. When you install or upgrade to ENS 10.5.5 or ENS 10.6.1, the utility automatically detects whether the endpoint has the faulty driver. If it does, the utility replaces it to resolve the issue. If a restart is needed, a prompt displays on the endpoint to perform a one-time restart. The restart must occur for the installation or upgrade to continue. When the faulty driver is replaced, future installations and upgrades do not require a restart for this issue. See the related article for more information.

ENSW-96252 ENSW-96169 ENSW-24290	KB92310	10.7.0	10.7.0 February 2020 Update	Issue: After you install or upgrade to the ENS Threat Prevention 10.7.0 extension, all Medium severity Exploit Prevention signatures change to enable the Block and Report setting within the McAfee Default policy. This function is a change from earlier ENS versions where Medium severity signatures have Block and Report disabled by default. This change can possibly generate false positives in your environment, depending on the signature and coverage details. Workaround: Use either of the following workarounds: Modify the ENS Threat Prevention Exploit Prevention policy assigned to the systems and disable the Block and Report setting for Medium severity signatures. Review the ENS Threat Prevention Exploit Prevention Medium severity events and determine whether a false positive event occurred. If the signature is not applicable to the environment, disable the signature. Resolution: This issue is resolved in ENS 10.7.0 February 2020 Update. See the related article for more information.
ENSW-27817	KB91830	10.7.0 10.6.1 July Update 10.5.5	10.7.0 February 2020 Update 10.6.1 December 2019 Update 10.5.5 December 2019 Update	Issue: Windows Security Center (WSC) intermittently reports that ENS is disabled. WSC can prompt to enable Windows Defender. Resolution: This issue is resolved in ENS 10.5.5 December 2019 Update, ENS 10.6.1 December 2019 Update, and ENS 10.7.0 February 2020 Update. See the related article for more information.
ENSW-25644	KB92104	10.7.0 10.6.1	10.7.0 February 2020 Update 10.6.1 December 2019 Update	Issue: McAfee-defined on-demand scans do not run with a standalone installation. But, custom-defined scans run and complete. Resolution: This issue is resolved in ENS 10.6.1 December 2019 Update and ENS 10.7.0 February 2020 Update. See the related article for more information.
ENSW-95857	KB92248	10.7.0	10.7.0 February 2020 Update	Issue: Network traffic via the SYSTEM process is being allowed by a McAfee core networking rule named "Allow McAfee signed applications". This fact affects SYSTEM-based network traffic, such as NetBIOS and SMB (for example, port 137, 138, and 445). If you created firewall rules to allow or block this type of SYSTEM-based network traffic, they do not apply. The reason is the "Allow McAfee signed applications" firewall rule is processed before any other firewall rules. Resolution: This issue is resolved in ENS 10.7.0 February 2020 Update. See the related article for more information.
ENSW-25728	KB91763	10.6.1	10.7.0	Issue: Blocking the protocols SSL v3 and TLS 1.0 leads to AMCore crashes. Resolution: This issue is resolved in ENS 10.7.0. See the related article for more information.
1237915		10.6.0	10.7.0	Issue: Triggering the Threat Prevention Access Protection rule "Executing Windows Subsystem for Linux" references IDS_AP_RULE_PREVENT_WSL_EXECUTEION:IDS_BLADE_NAME_SPB when describing the violated rule. IDS_AP_RULE_PREVENT_WSL_EXECUTEION:IDS_BLADE_NAME_SPB is a reference for the Access Protection rule "Executing Windows Subsystem for Linux". Resolution: This issue is resolved in ENS 10.7.0. With ENS 10.7.0, IDS_AP_RULE_PREVENT_WSL_EXECUTEION:IDS_BLADE_NAME_SPB is translated to the Access Protection rule "Executing Windows Subsystem for Linux".
1234300		10.5.3	10.7.0	Issue: When viewing the ENS Threat Prevention Exploit Prevention policy, the Signatures table includes an Action to Export Table. When exporting the signatures list to any file formats, the Status and Type columns are blank. Resolution: This issue is resolved in ENS 10.7.0. With ENS 10.7.0, the Export Table function for Exploit Prevention signatures correctly exports the data in the Status and Type columns.

Microsoft Edge browser issues:

Reference Number	Related Article	Found in ENS Version	Resolved in ENS Version	Issue Description
1273919		10.6.1		Issue: The ENS Web Control extension is not installed and can't be enabled in the Edge browser after an in-place upgrade of Windows. Workaround: Enable the ENS Web Control extension in Edge as follows. Close Edge. Go to the following location: 32-bit: C:\Program Files\McAfee\Endpoint Security\Web Control 64-bit: C:\Program Files (x86)\McAfee\Endpoint Security\Web Control Open the file McAfeeWebControl.appx. An installation prompt appears. Follow the prompt and install the app package. Close the prompt. Open Edge. An Enable WC Extension prompt appears. Click Enable.
1254789		10.6.1		Issue: The Edge extension does not load on Microsoft Windows 10 Fall Creators Update and Windows 10 Creators Update even though the extension is licensed. A license issue reported by Microsoft causes this issue. McAfee is working with Microsoft on this issue. NOTE: The Edge extension is not supported on Windows 10 Anniversary Update. The reason is because the native messaging that is needed to communicate between the extension and the Win32 process was introduced in Windows 10 Fall Creators Update. Workaround: The Edge extension is supported only on Windows 10 April 2018 Update and later.
		10.6.1		Issue: There is no group policy exposed to allow the ENS Web Control extension to use the InPrivate mode of the Edge browser. Workaround: Manually allow the extension in InPrivate mode.
ENSW-13888		10.6.1		Issue: The ENS Web Control toolbar icon does not show the correct color depending on the rating of the website while switching between tabs. This issue occurs intermittently.
		10.6.1		Issue: On Windows 10 April 2018 Update, users can disable the Edge extension and bypass ENS Web Control protection. Workaround: Windows 10 October 2018 Update provides a group policy (Prevent turning off required extensions) to harden the Edge extension. To make sure that users can't disable the Edge extension, add the ENS Web Control extension PFN to the group policy Prevent turning off required extensions. The ENS Web Control extension PFN is the following and can be fetched from the Dev Center portal: 5A894077.McAfeeEndpointSecurityWebControl_wafk5atnkzcwy. For detailed instructions to enable this group policy, see https://docs.microsoft.com/en-us/microsoft-edge/deploy/new-policies#prevent-turning-off-required-extensions.

All other non-critical issues:

Reference Number	Related Article	Found in ENS Version	Resolved in ENS Version	Issue Description
ENSW-97123		10.7.0 February 2020 Update		Issue: When you upgrade from ENS 10.5.5 (with Web Control version 10.5.5.5221) to ENS 10.7.0 February 2020 Update, applications that have wcHook.dll loaded might crash during the upgrade. Workaround: To work around the issue: Download and run Microsoft Process Explorer. Click Find. Select Find handle or DLL. Enter wcHook.dll and click Search. Close any application that has wcHook.dll loaded. Continue with the upgrade from ENS 10.5.5 to ENS 10.7.0 February 2020 Update.
ENSW-96726		10.7.0 February 2020 Update		Issue: The ENS debug log might contain the following error during agent policy enforcement. Despite this error, the on-demand scan policies are applied properly. 2020-01-22 01:37:27.691Z\|Error \|MaSpb \|mfetp \| 10052\| 2260\|MaSpb \|msgbus_EnforcePolicies.cpp(2144) \| Failed to enforce ODS policies. Error: 0xfffe
ENSW-96725		10.7.0 February 2020 Update		Issue: If a custom path is configured for Client logging, the ENS Product Logs folder might still exist after ENS is uninstalled.
ENSW-96724		10.7.0 February 2020 Update		Issue: The Limit maximum CPU usage option remains grayed out when Scan anytime is selected in the ePolicy Orchestrator extension.
ENSW-96670		10.7.0 February 2020 Update		Issue: mctray.exe might terminate unexpectedly when you update content via the V3 DAT exe. Workaround: Run the V3 DAT exe again to restart mctray.exe.
ENSW-96274		10.7.0 February 2020 Update		Issue: In rare scenarios, the Threat Prevention policy changes might not be enforced on the client after the first agent-to-server communication. Workaround: Settings get applied at the next agent-to-server communication of policy enforcement.
ENSW-29499		10.7.0 February 2020 Update		Issue: When you deploy McAfee Agent using the self-agent deployment URL, if the Browsers launching files from the Downloaded Program Files folder Threat Prevention Access Protection rule is set to Report, the Target Signed field in the resulting Access Protection event for McAfeeSmartInstall.exe is set to No.
ENSW-27455		10.7.0 February 2020 Update		Issue: You might see Security Audit Failure messages in Event Viewer for amcfg.exe. There is no functional impact to ENS.
ENSW-96720	KB92412	10.7.0		Issue: After you install or upgrade to ENS 10.7.x, the Firewall module blocks legitimate network traffic responses. Workaround: Create a rule within the ENS Firewall rules policy to allow the traffic. See the related article for more information.
ENSW-29514		10.7.0		Issue: ENS upgrades use the cached ENS MSI databases. If you have deleted the cached ENS MSI databases from the C:\Windows\installer directory, ENS upgrades fail. Workaround: To prevent this issue from occurring, do not upgrade ENS. Instead, uninstall the current version of ENS and then install the new version of ENS. If you have already encountered an upgrade failure, use the Endpoint Product Removal (EPR) tool to remove ENS and clean up the system. Then, install the new version of ENS. For more information about the EPR tool, see KB90895.
ENSW-94600	KB92258	10.7.0		Issue: When you install ENS 10.7.0 using the standalone installer, and supply the verbose logging switch (for example, "setupEP.exe ADDLOCAL="tp,atp,fw" */lv"C:\temp\"), the ENS installer does not write anything to the logs, does not install, and almost immediately exits. Workaround:** To allow the successful installation of ENS using the standalone installer, remove the verbose logging switch from the command-line argument passed to the standalone installer. See the related article for more information.
TSDE-2913	KB92154	10.7.0		Issue: When Windows Defender has content older than 1.295.49.0, it might generate a false-positive on one or more ENS installation files. As a result, the installation or upgrade of ENS fails or only partially succeeds. Workaround: Before the install or upgrade of ENS, make sure that Windows Defender content is current or that Windows Defender is disabled. Resolution: After you update the Windows Defender content or disable Windows Defender, the next attempt to install or upgrade ENS might succeed. If not, the failed installation might require removal first. See the related article for more information.
ENSW-29097		10.7.0		Issue: A blue screen error (system crash) might occur when you try to upgrade to ENS 10.7 on Windows 10 Version 1709 (Fall Creators Update) and earlier. Workaround: This issue is an operating system issue that Microsoft resolved in Windows 10 Version 1803 (April 2018 Update) and later. Before you upgrade to ENS 10.7, upgrade to Windows 10 Version 1803 (April 2018 Update) or later.
ENSW-28427		10.7.0		Issue: When you upgrade from VirusScan Enterprise (VSE) 8.8 Patch 9 (and earlier) to ENS 10.7, VSE remnants might be left behind. Workaround: The following workarounds are available: Uninstall VSE before you install ENS 10.7. Upgrade VSE to 8.8 Patch 10 (or later) and then upgrade to ENS 10.7.
ENSW-28315		10.7.0		Issue: When you upgrade from Windows Server 2008 R2 to Windows Server 2019, the option to retain apps and data is disabled. Workaround: Upgrade the operating system from Windows Server 2008 R2 to Windows Server 2019 before installing ENS.
ENSW-28558		10.6.1 October Update		Issue: In an environment that uses Microsoft System Center Configuration Manager (SCCM), installation or upgrade of the Web Control module might fail.
ENSW-28517		10.7.0 10.6.1 October Update 10.5.5 October Update		Issue: After you upgrade from ENS 10.5.5/10.6.1 July Update to ENS 10.5.5/10.6.1 October Update or ENS 10.7, the mctray.exe process might become unresponsive. Workaround: To resolve the issue, restart the system.
ENSW-28356	KB92387	10.6.1 July Update		Issue: An Exploit Prevention alert is triggered even if it is disabled after importing ENS settings with the ESConfig tool. Workaround: Reboot the operating system after importing ENS settings with the ESConfig tool. After the reboot, Exploit Prevention alerts are not triggered if they are disabled. See the related article for more information.
ENSW-28377 ENSW-28356	KB92305	10.7.0 10.6.1 July Update		Issue: Exploit Prevention is disabled and signature ID 344 is disabled. But, the following event for signature ID 344 gets generated. See the related article for more information. New Startup Program Creation
ENSW-96956	KB92372	10.6.1		Issue: After you upgrade from SCCM 1906 or earlier to SCCM 1910, a Windows 10 in-place upgrade task sequence might hang on a system with ENS installed. Workaround: You can either revert to using the previously known working version SCCM 1906 or earlier, or try implementing the workarounds in the related article.
1269846	KB91409	10.6.1		Issue: The application mfetp.exe crashes at module MSVCR100.dll. Workaround: If an Exploit Prevention application protection rule is configured with over 50 executables, mfetp.exe crashes. Modify the Exploit Prevention application protection rule so that it has a maximum of 50 executables. See the related article for more information.
1258147	KB91344	10.6.1		Issue: Issues can occur in Microsoft Excel when the add-in option "Solver" is enabled. Excel might crash, fail to load, or fail to apply the Solver add-in as expected in a cell. Workaround: ENS Web Control is not currently compatible with the Excel Solver add-in. To use the Solver add-in, you must uninstall ENS Web Control from the system. See the related article for more information.
1266885 1245446 1245515	KB91411	10.6.0		Issue: ENS for Windows does not support the Microsoft Windows Subsystem for Linux (WSL) feature. There are known compatibility issues with ENS and WSL. Resolution: McAfee is investigating adding support for WSL for future ENS releases. See the related article for more information.
1214940 1207506	KB90041	10.6.0		Issue: ENS for Windows does not support Windows dockers. Resolution: McAfee is investigating making ENS for Windows compatible with containers for future ENS releases. See the related article for more information.
1238699		10.6.0		Issue: The Firewall Rule policy hangs in ePolicy Orchestrator 5.10 when a non-administrator user submits a policy for approval.
1238665		10.6.0		Issue: Threat Prevention Exploit Prevention exclusions with "Allow any signature" incorrectly match processes that have no signature. "Allow any signature" must only match if the process is signed.
1238526		10.6.0		Issue: If the ePolicy Orchestrator administrator selects an Exploit Prevention event with ID 18056 in the Exploit Prevention Events log, and chooses Action, Add Exclusion, the resulting exclusion does not work. (Event ID 18056 indicates Buffer Overflow detected and blocked (DEP).) Workaround: The following workaround disables all ENS Buffer Overflow and Illegal API Use protection for the associated process. Edit the added exclusion in the associated Exploit Prevention policy. Remove the signature ID (9990) from the exclusion. Save the exclusion and policy.
1238510		10.6.0		Issue: When you create a Buffer Overflow exclusion where the Signature ID or API is specified and the exclusion is based on an Exploit Prevention event, signer SDN matching does not work. Workaround: Reverse the order of the SDN element provided by the event. For example, if the threat event details specify the SDN as: O=MCAFEE, OU=ENGINEERING, CN=TEST Reverse the SDN order to: CN=TEST, OU=ENGINEERING, O=MCAFEE
1235491		10.6.0		Issue: For Antimalware Scan Interface (AMSI) file detections, where the First Action is Delete and the delete fails, the detection event incorrectly shows the Second Attempted Action as Not Available. No workaround is needed. The Second Attempted Action is Block and correctly blocks the activity.
TSDE-2145	KB91661	10.5.5 July Update 10.6.1 July Update		Issue: ENS Firewall 10.5.5/10.6.1 July Update blocks ENS ATP (mfeatp.exe) network communication. The ENS FirewallEventMonitor.log shows the following. See the related article for more information. Time: 07/12/2019 04:00:29 PM Event: Traffic IP Address: ###.###.###.### Description: MCAFEE ADAPTIVE THREAT PROTECTION SERVICE Path: C:\PROGRAM FILES\MCAFEE\ENDPOINT SECURITY\ADAPTIVE THREAT PROTECTION\MFEATP.EXE Message: Blocked Outgoing TCP - Source ###.###.###.### : (30823) Destination ###.###.###.### : https (443) Matched Rule: Block all traffic
ENSW-27771	KB92206	10.5.5		Issue: ENS does not honor the option Use system proxy settings for proxy settings on Windows Server Core. This fact results in the following issues: Global Threat Intelligence (GTI) and TrustedSource connectivity do not work if the network traffic has to go through the proxy. Detections that depend on GTI and TrustedSource are not detected. AMCore and Exploit Prevention content updates do not work on an unmanaged client. Workaround: Explicitly set the proxy server. See the related article for more information.
1254885		10.5.5		Issue: The McAfee Endpoint Security link does not open from the Virus & threat protection section of Windows Defender Security Center after you upgrade to ENS 10.5.5 from an older version.
ENSW-25754 1243609	KB90765	10.5.3		Issue: After you uninstall the ENS Firewall module, all incoming traffic to the client is blocked. Workaround: To prevent the issue, disable the ENS Firewall before you uninstall the module. In your assigned ENS Firewall Options policy, deselect the option Enable Firewall. If you are uninstalling the ENS Firewall module locally, disable ENS Firewall through the ENS Console. On clients that are already affected, reinstall ENS Firewall, disable ENS Firewall through your assigned policy, and uninstall the ENS Firewall module. See the related article for more information.
1215521		10.5.3		Issue: An upgrade to ENS Firewall 10.5.3 hangs. Workaround: Perform the relevant option below: For an ePolicy Orchestrator (ePO) managed environment: Create an ePO deployment task for the upgrade, and specify the following command-line parameter in the Command line text field: -nopreservesettings The parameter skips preserving settings during the upgrade and installs with the default policy. The client gets the customized policy in the next policy enforcement interval. For a standalone environment: Do not select the Preserve Settings checkbox in the installation wizard during the upgrade.
1213517		10.5.3		Issue: Communication is blocked for Microsoft Edge with Application Guard when you use ENS Firewall. Workaround: Create a firewall rule with the following criteria: Allow Inbound TCP/IPv4 and TCP/IPv6, Local Ports 80 and 443 (or just the proxy port, when appropriate), Remote Ports 49700–65535, Virtual Media. McAfee is investigating whether further qualifying criteria can be set for this rule to avoid the issue. This article is updated if new information becomes available. NOTE: This rule also matches for VPN adapters. VPN traffic matching is disrupted.
1212361		10.5.3		Issue: After installation the ENS Web Control module reports as "Not started" in the ENS console. Workaround: To fix the issue, restart the system.
1203341	KB89678	10.5.2		Issue: A compatibility issue exists between McAfee Application and Change Control (MACC) and ENS that might cause ENS install or upgrades to fail. Workaround: To make sure that MACC and ENS can coexist on an endpoint, disable the MACC memory protection and script as updater features. See the related article for instructions to disable these features and for direction on how to install or upgrade the ENS and MACC software.
ENSW-25740 1187479	KB89817	10.5.1		Issue: When an ENS Firewall rule is created using the Range option with either a single IP address or an IP subnet, the ENS Firewall Client Console displays an incorrect Address Type (for example, Subnet). See the related article for more information.
1155117		10.5.0		Issue: You can't create a Threat Prevention Access Protection user-defined rule (also called custom rule) to include or exclude files that have no extension. ENS does not allow the administrator to distinguish between a file or folder when creating Threat Prevention Access Protection custom rules. This fact prevents the creation of custom rules that include or exclude files that have no extension.
1147465		10.5.0		Issue: There is no option to set a warn action for a website rated with a specific Web Category present in the Content Actions policy. (A warn action to display a warning page to the user to either continue or cancel the navigation of a website.) Only allow or block actions are available to configure for any website rated with a specific Web Category.
1106888		10.5.0		Issue: Exclusions are not added to allow System Information Reporter 1.0 to work properly when the SIR Set Registry policy is changed.
971929 971928	KB82371	10.5.0		Issue: ENS Web Control reports in ePolicy Orchestrator can show a functional status for ENS Web Control in Chrome, Firefox, and Internet Explorer, and show in the report as True, Indeterminate, or False. But, on some systems the computer can incorrectly report back a functional status of False. Workaround: Use the ENS Web Control property enabled. See the related article for more information.

1258029		10.6.1	As Designed	Issue: Search annotations do not display in Mozilla Firefox or Google Chrome when searching in Google. Resolution: This behavior is as designed.
1268197	KB91559	10.6.1	As Designed	Issue: The ENS installation fails. The Common BootStrapper log shows the following error: [BootstrapperMain] RunCommandLine: Process return code : 4294967295 [BootstrapperMain] !> Error - Could not run command to uninstall vscore helper util: -1 [BootstrapperMain] VSCore uninstall helper failed. Returning!! Resolution: This behavior is as designed. The ENS installation and product functionality work when minRSAPubKeyBitLength is set to the default value of 1024 bits. If you have overridden the default value, review and determine whether there is a compelling reason for the adjusted value. See the related article for more information.
1254844		10.6.1	Will Not Fix	Issue: ENS Web Control block pages are not displayed in iFrames in the Edge browser for Red and Yellow URLs directly in the iFrame page. When opening the page in a new window, a partial ENS Web Control block page appears. Resolution: This issue will not be resolved.
1253322		10.6.1	Will Not Fix	Issue: The ENS Web Control Enforcement Messaging messages are truncated for Polish and Russian in the ePolicy Orchestrator policy. Resolution: This issue will not be resolved.
1259082		10.6.0	As Designed	Issue: Upgrading the ENS 10.5.5 extension to 10.6.0 is not supported. The upgrade fails with the following error: Unable to install extension. Upgrade from version 10.5.5.5033 is not supported. Resolution: Upgrade to ENS 10.6.1 instead. This behavior is as designed. ENS 10.5.5 has a new feature "Client UI lock out" that is not available in ENS 10.6.0. Allowing the upgrade would cause deprecation of this feature. So, ENS blocks this upgrade.
		10.6.0	As Designed	Issue: When using the Help feature (clicking the "?" question mark) in the ePolicy Orchestrator console, a web browser page opens to https://docs.mcafee.com/, instead of a contextual page of product information. Resolution: This behavior is as designed with the Help feature starting with ENS 10.6.0. It will be the functionality for all future versions.
1263066 1239337		10.6.0	Will Not Fix	Issue: If you use the Mozilla Firefox, Google Chrome, or Microsoft Edge browser, ENS Web Control email annotation banners do not appear when malicious URLs are present in the body of the email. Resolution: This issue will not be resolved. To see ENS Web Control email annotation banners when malicious URLs are present in the body of an email, use the browser Microsoft Internet Explorer.
1240425	KB90664	10.6.0	Unable to reproduce	Issue: On rare occasions, in the presence of Adaptive Threat Protection, an ENS upgrade from 10.5.0 (and later) to 10.6.0 fails, thus causing the system to enter a non-protective state. The following symptoms are observed when the issue occurs: The content update fails continuously and the product properties of the system show the old AMCore that was updated last. Threat Prevention and Adaptive Threat Protection show the previous versions whereas Endpoint Security Platform shows 10.6.0 in the product properties for the respective endpoint. The Endpoint Security Console shows Threat Prevention and Adaptive Threat Protection in a "Not Started" state. The Threat Prevention and Adaptive Threat Protection version information is not displayed in the About dialog box. The mfetp, mfeatp, and mcshield processes stop running on the endpoint. EICAR or any malware detection fails on the endpoint. Resolution: To resolve the issue, McAfee has released a tool that can be deployed using ePolicy Orchestrator. See the related article for more information.
1233664		10.6.0	As Designed	Issue: ENS Web Control does not allow a clean file to download from a malicious URL based on reputation, if McAfee Client Proxy is in redirection mode. Resolution: This behavior is as designed. The file is not downloaded because of a double enforcement by ENS Web Control and McAfee Client Proxy. The recommendation is to enable the setting Disable if McAfee Client Proxy is detected in the ENS Web Control Options policy.
1228925		10.6.0	As Designed	Issue: ENS installation might fail on a system with older update levels of Host Intrusion Prevention 8.0. Resolution: This behavior is as designed. Upgrade Host Intrusion Prevention 8.0 to one of the following: Host Intrusion Prevention 8.0 Update 11 February 2018 content release 8231 (or later) if using Host Intrusion Prevention 8.0 Update 7 or earlier March 2018 content release 8274 (or later) if using Host Intrusion Prevention 8.0 Update 8 through 10
1228409	KB90374	10.6.0	Will Not Fix	Issue: If you install ENS Web Control on a system with Application and Change Control 8.1.0.118.1 present, the Google Chrome Endpoint Security Web Control Extension is disabled. (It is grayed out.) So, no sites are blocked and no ratings are shown. Resolution: This issue will not be resolved. See the related article for instructions to prevent the issue from occurring before installing ENS Web Control. Or, to resolve the issue if you have already installed ENS Web Control and have experienced the issue.
	KB88765	10.5.3	As Designed	Issue: If the ENS Web Control iFrames support feature blocks a site, adding the site to the ENS Web Control Allow List does not allow access to the site. Resolution: This behavior is as designed. See the related article for more information. Use any of the following options to allow access to sites that the iFrames support feature blocks: Add the IP address of the web server to the Exclusions list in the ENS Web Control Options policy. Change the action specified for sites that are rated as Yellow and Unrated to Allow in the ENS Web Content Actions policy. Sites that are rated as Yellow and Unrated are blocked if the action specified for these sites is set to Warn and they appear in an HTML iFrame. Disable the option Enable HTML iFrames support in the ENS Web Control Options policy.
1232358		10.5.3	Unable to reproduce	Issue: Access Protection rules for the Threat Prevention module are not visible in the ePolicy Orchestrator console. An export of the policy (to XML) reveals that the value assigned to "APRules.dwAPRuleBlocks" does not match the actual number of rules. Workaround: Delete the corrupt policy, and create a new policy. Currently the cause of the corruption is unknown.
1229445		10.5.3	Crowdstrike hotfix is available	Issue: A system crash (blue screen error) occurs in mfencbdc.sys when installing ENS with the third-party software Crowdstrike present on the system. Resolution: A hotfix is available from Crowdstrike to resolve the issue.
1216519		10.5.3	Will Not Fix	Issue: After installation, the ENS Web Control module is not reporting to ePolicy Orchestrator. Resolution: This issue will not be resolved. To fix the issue, restart the system.
1215828		10.5.3	Will Not Fix	Issue: Microsoft Data Execution Prevention (DEP) integration is working, but events are not reported for buffer overflow attacks with standalone installations. Resolution: This issue will not be resolved. DEP event reporting works as expected with ePolicy Orchestrator.
1215800		10.5.3	As Designed	Issue: An upgrade of the ENS 10.5.3 Firewall, Threat Prevention, or Web Control modules through an ePolicy Orchestrator (ePO) deployment task from RTS to GA does not automatically upgrade the Host Common module. The Host Common module stays at the RTS version unless explicitly included in the ePO deployment task. Resolution: This behavior is as designed. Add the Host Common module to the ePO deployment task when upgrading from ENS 10.5.3 RTS to ENS 10.5.3 GA.
1215784		10.5.3	As Designed	Issue: An upgrade fails from VirusScan Enterprise 8.8 Update 4 + Host Intrusion Prevention 8.0 Update 4 + SiteAdvisor Enterprise 3.5 Update 2 to ENS 10.5.3. Resolution: This behavior is as designed. Update the Host Intrusion Prevention content before the upgrade to avoid this issue.
1215537	KB89293 KB86948	10.5.3	As Designed	Issue: On Windows Server operating systems, web protection is not blocking malicious sites in Internet Explorer 11. Resolution: This behavior is as designed. On Windows Server operating systems, the Internet Explorer browser setting "Enable third-party browser extensions" is disabled by default. ENS Web Control requires this option to be enabled. For instructions to enable this option, see the related articles.
1214616		10.5.3	As Designed	Issue: In an ePolicy Orchestrator (ePO) deployment, the ENS installation is interrupted leaving only the Platform installed. Cause: Another application restarts the system after the Platform installation. Because of the restart, the McAfee Agent deployment task is abruptly closed, which can cause ePO to not receive any response and then time out. Resolution: This behavior is as designed. Send another deployment task to the systems with this issue. The ENS installation succeeds.
1209000		10.5.3	As Designed	Issue: Access Protection File execute and Process run subrules and operations are not working. Resolution: This behavior is as designed. The service "McAfee Validation Trust Protection Service" allows trusted applications to function when needed. This service mitigates the risk of creating a rule accidentally that might potentially prevent an essential process from running, and even impact the normal behavior of the operating system. The validation is applied only to some specific rules that are trusted from McAfee and Microsoft. The validation is applied by default to all rules when created using the Access Protection user interface. But, the validation is not applied by default for expert rules for Exploit Prevention.
		10.5.2	As Designed	Issue: Running the migration tool more than once can cause policies to be overwritten and appear to revert. Resolution: This behavior is as designed. The policy migration task is intended to be run only once and from that point not run again in the environment.
	KB89510	10.5.1 Hotfix 2	As Designed	Issue: After you install an ENS update or hotfix that upgrades AMCore, the AMCore scanner fails to initialize. On-Access Scanning and On-Demand Scanning do not work if the AMCore scanner does not initialize. Resolution: This behavior is as designed. Anytime an ENS update or hotfix upgrades AMCore, it is mandatory to update to current AMContent for the AMCore scanner to initialize. See the related article for more information.
	KB89509	10.5.1 Hotfix 2	As Designed	Issue: After installation of ENS 10.5.1 Hotfix 2, the following issues can occur: The AMCore content version is reported as .5. After the hotfix installation, a content update will run and download new content. If the ENS 10.5.1 and ENS 10.5.1 Hotfix 2 packages are in the same branch of the Master Repository, the ENS 10.5.1 package is downloaded to the end node at each McAfee Agent agent-server communication interval (ASCI). Resolution: This behavior is as designed. The new version of AMCore with ENS 10.5.1 Hotfix 2 requires AMContent 3004 or higher (released June 7, 2017). Also, ENS 10.5.1 and ENS 10.5.1 Hotfix 2 can't be in the same branch of the ePolicy Orchestrator Master Repository. See the related article for more information.
	KB89534	10.5.1 Hotfix 2	As Designed	Issue: An AMCore content update fails if you check in ENS hotfix packages to a different branch than Current in the ePolicy Orchestrator Master Repository. Resolution: This behavior is as designed. The next scheduled content update task from ePolicy Orchestrator will resolve the issue. To avoid this issue, make sure that there is a copy of AMCore content in both of the branches. See the related article for more information.
	KB89469	10.5.1 Hotfix 1	As Designed	Issue: An upgrade from ENS 10.5.0 to ENS 10.5.1 fails if ENS 10.5.1 Hotfix 1 or Hotfix 2 is in the same branch of the ePolicy Orchestrator Master Repository. Resolution: This behavior is as designed. ENS 10.5.1 and ENS 10.5.1 Hotfix 1 or Hotfix 2 can't be in the same branch of the ePolicy Orchestrator Master Repository. See the related article for more information.
1226114		10.5.1	Unable to reproduce	Issue: ENS Web Control site ratings do not appear on the second page of results when using Internet Explorer 11 and the Bing search engine with the region set to English United States. Workaround: Refresh the page and the site ratings appear.
1201666		10.5.1	As Designed	Issue: A Potentially Unwanted Program exclusion by detection name is not applied to detections through the scan email attachments feature. Resolution: This behavior is as designed. Disable the scan email attachments feature if you see too many detections.
1185352		10.5.1	Will Not Fix	Issue: If McAfee Client Proxy is uninstalled and reinstalled on a system with ENS 10.5.1, and "Disable if McAfee Client Proxy is detected" is enabled in the ENS Web Control Options policy, that setting is not honored unless it is disabled and re-enabled. Resolution: This issue will not be resolved. Disable "Disable if McAfee Client Proxy is detected" in the ENS Web Control Options policy, and check the new policies. Then, re-enable "Disable if McAfee Client Proxy is detected" in the ENS Web Control Options policy, and again check the new policies.
1183560		10.5.1	Will Not Fix	Issue: The RESTORE operation for registry-related Access Protection subrules is not working as expected when it is the only operation enabled on the Access Protection subrule. Resolution: This issue will not be resolved. Enable REPLACE, DELETE, and WRITE operations with the RESTORE operation when defining a Registry Key or Registry Value Access Protection subrules.
1180078		10.5.1	Will Not Fix	Issue: If the user selects more than 1000 files and performs a right-click on-demand scan on the selection, only 1000 of the files are scanned. Resolution: This issue will not be resolved. When performing a right-click on-demand scan of more than 1000 items, select the parent folder instead of the files in it.
1175803		10.5.1	As Designed	Issue: The "AMCore Content Compliance Days" property stays empty in all situations, for both Compliant and Noncompliant content. Resolution: This behavior is as designed. The "AMCore Content Date" property was added to Queries, making the "AMCore Content Compliance Days" property obsolete.
1173540		10.5.1	Will Not Fix	Issue: The following migration issues occur when the ENS Firewall extension is not installed: Manual migration does not allow you to migrate VirusScan Enterprise Access Protection and Buffer Overflow Protection policies, and Host Intrusion Prevention IPS policies, to ENS Threat Prevention policies. Auto migration does not migrate trusted applications for IPS to the Access Protection policy as global exclusions. The policy naming convention is different. The policy is named "Migrated VSE Policy-n" rather than "Merged Policy -n". Resolution: This issue will not be resolved. Install the ENS Firewall extension even though you do not use the Host Intrusion Prevention firewall features.
1184610		10.5.0	Will Not Fix	Issue: Services protection does not block some services from starting. This issue has been reported with the Security Center Service and Bluetooth Support Service. Resolution: This issue will not be resolved.
1180296	KB87096	10.5.0	As Designed	Issue: Installation of ENS fails. The installation logs contain error code 0x80096005, -2146869243, or both. Cause: The required trusted root certificates were not added during installation. Resolution: This behavior is as designed. Address the issue preventing the automatic update of root certificates, or import the required root certificates. See the related article for more information.
1167969		10.5.0	As Designed	Issue: Services protection has the following limitations (that also exist in Host Intrusion Prevention): User and executable parameters are not distinguished; although they are available in the UI, they are not valid parameters. Services protection is valid up to Windows 8.0; later releases are not supported. The enable or disable hardware profile operation is not supported. Resolution: This behavior is as designed.
1165257		10.5.0	As Designed	Issue: A user can continue to change settings after a time-based password has expired if the console to the settings is still open before the password expires. The next policy enforcement will override the changed settings. Resolution: This behavior is as designed.
1163884		10.5.0	As Designed	Issue: After you disable firewall timed groups, time ticking is paused when the firewall is disabled, and starts from the point in time when the firewall is re-enabled. Even though timed groups are enabled, they are not functional because the firewall is disabled. Resolution: This behavior is as designed. When the firewall is re-enabled, re-enable the timed group and change its running time in the policy. To stop the timed group, use the Disable Firewall Timed Group option in the McTray Quick Settings.
1162830 926640	KB76802	10.5.0	Will Not Fix	Issue: When ENS Web Control is installed on an operating system that has Internet Explorer with the Enhanced Protected Mode setting enabled, it fails to block malicious sites and file downloads. ENS Web Control is not compatible with Internet Explorer Enhanced Protected Mode. Resolution: This issue will not be resolved. See the related article for instructions to disable Enable Enhanced Protected Mode in Internet Explorer.
1157387		10.5.0	As Designed	Issue: You install ENS, enable Disable if McAfee Client Proxy is detected in the Options policy of ENS Web Control, enforce the policy, and then install McAfee Client Proxy. But, ENS Web Control is not disabled immediately after the installation of McAfee Client Proxy. Resolution: This behavior is as designed. Use either of the following workarounds: Wait for about five (5) minutes, and ENS Web Control is disabled. Change any ENS Web Control policy and enforce the new policy, and ENS Web Control is disabled.
1154452		10.5.0	Will Not Fix	Issue: When you select a sub System Tree ENS migration, select some groups, click Actions, choose columns, and save, the selection of groups is reset. Resolution: This issue will not be resolved.
1151514		10.5.0	Will Not Fix	Issue: Block and Report settings of the Exploit Prevention policy are not set when the Host Intrusion Prevention Rules Policy is not edited, but the IPS Protection policy is changed. When the Host Intrusion Prevention Rules Policy is not edited, but the IPS Protection policy is changed with the Reaction as either Log or Ignore, the Migration Assistant does not migrate Host Intrusion Prevention Rules. The ENS settings are set to the default behavior. Resolution: This issue will not be resolved. This issue is an unlikely scenario where the Host Intrusion Prevention Rules policy is not edited and the dependent IPS Protection policy is changed to a lower Reaction for high severity signatures. Even though this configuration would have been made by mistake, ENS defaults to correct the behavior with setting the Block setting.
1077660		10.5.0	Will Not Fix	Issue: If a McAfee Agent update task is configured to show the update progress window, and the user is allowed to postpone the task, the "Update in Progress" window might appear for a short time. It appears even though the update is not actually occurring. If the user postpones the task, an "Update finished" window might appear, even though the update did not occur. Resolution: This issue will not be resolved.
	KB87568	10.5.0	As Designed	Issue: The ENS Web Control browser extensions must be enabled in the browser before ENS Web Control is operational in the browser. Resolution: This behavior is as designed. See the related article for more information.
1179636	KB88568	10.5.0	Unable to reproduce	Issue: A scan exclusion configured for multiple mount points does not work. Workaround: Configure the scan exclusion with the full path for the mount point. If you experience this issue, contact Technical Support. See the related article for more information.
1163246		10.5.0	Will Not Fix	Issue: McAfee Agent 5.0.2.132 does not upload the ENS 10.x events. Resolution: This issue will not be resolved. Use McAfee Agent 5.0.2.333 or later.
1144915		10.5.0	Will Not Fix	Issue: After all ENS modules are uninstalled, the Common module (Endpoint Security Platform) uninstallation is automatically started. Sometimes the user interface for this uninstallation is minimized, which can make it harder for a user to tell when this uninstallation is occurring. Cause: The Endpoint Security Platform is a support module that is needed for the ENS protection modules to function. When all other modules are uninstalled, the Endpoint Security Platform module is automatically removed. But, Windows sometimes starts this process in a minimized mode or show the window behind the other windows on the screen. If the user does not know that this uninstallation is happening, they could inadvertently restart the system in the middle of that uninstallation. Resolution: This issue will not be resolved. Before you uninstall ENS products, make sure that any current work is saved, and close running desktop programs. The user can likely see that the Endpoint Security Platform uninstallation is occurring.
1148403		10.5.0	Will Not Fix	Issue: If you upgrade the Threat Prevention extension version, the ENS client UI might fail to display Exploit Prevention exclusions, indicate erroneous validation errors, and generate errors in EndpointSecurityPlatform_Errors.log such as the following: Failed to retrieve GPEP setting for Exploit Prevention. Failed to enforce Exploit Prevention policies. Resolution: This issue will not be resolved. Edit and save the assigned Exploit Prevention policy, and send an agent wake-up call to the affected systems.
1142553	KB87534	10.5.0	Unable to reproduce	Issue: On Windows 7, user roaming profiles are not saved to a network share on user logoff. Workaround: Create an exclusion in Threat Prevention to not scan the roaming profile folders on the server. See the related article for more information. Currently a root cause can't be found on Windows 7. If you experience the issue with Windows 8 or Windows 10, collect the information described in the related article and provide the results to Technical Support.
1137118		10.5.0	Will Not Fix	Issue: During upgrade from a previous version of ENS, when Save my settings if upgrading is deselected, the user provided Access Protection exclusions remain on the system. Resolution: This issue will not be resolved. Remove unwanted Access Protection exclusions; use the ENS Console before the upgrade to the latest version of ENS.
1137117		10.5.0	Will Not Fix	Issue: During upgrade from a previous version of ENS, when Save my settings if upgrading is deselected, the user provided Exploit Prevention exclusions partially remain on the system. Resolution: This issue will not be resolved. Remove unwanted Exploit Prevention exclusions; use the ENS Console before the upgrade to the latest version of ENS.
1134953		10.5.0	Will Not Fix	Issue: If you use Firefox, when ENS Web Control blocks the download of a malicious file, a zero-byte file is left in the folder in which the file was being downloaded. Resolution: This issue will not be resolved. Use a different browser, such as Internet Explorer or Chrome.
1132923		10.5.0	As Designed	Issue: When you select the IPS Rules policy for migration, the IPS Protection policy category lists all policies from the Policy Catalog including McAfee defined and unmodified My Default policies. Resolution: This behavior is as designed.
1132406		10.5.0	Will Not Fix	Issue: SiteAdvisor Enterprise policies named Typical Corporate Environment are not migrated in a manual migration or one-to-one auto migration. Typical Corporate Environment is a default policy name for a few products that are not migrated. The Migration Assistant does not migrate policies with this name for any products. Resolution: This issue will not be resolved. Rename the SiteAdvisor Enterprise policy from Typical Corporate Environment to any other name and then perform the migration.
1132404		10.5.0	Will Not Fix	Issue: Manual migration is allowed to continue when only the IPS protection policy is selected. Resolution: This issue will not be resolved.
1132212		10.5.0	Will Not Fix	Issue: Auto-migrated Threat Prevention Access Protection and XP policies do not include the IPS Protection policy in their notes section. Resolution: This issue will not be resolved.
1131595		10.5.0	Will Not Fix	Issue: Executable notes from Host Intrusion Prevention Exceptions do not migrate to the Exploit Prevention executable notes section. Resolution: This issue will not be resolved.
1129727		10.5.0	Will Not Fix	Issue: If a Host Intrusion Prevention file, reg, or program rule exception contains multiple parameter types, such as user name and executable, the exception applies when all parameters are true. After migration to an ENS Access Protection rule, the exception applies when any of the parameters are true. Resolution: This issue will not be resolved. In ENS, create one rule per parameter type.
1127732		10.5.0	As Designed	Issue: The TIE client sends only TIER 1 requests for known trusted files signed by a certificate. Resolution: This behavior is as designed.
1120973		10.5.0	As Designed	Issue: When you perform a Secure Search from the search bar, it does not automatically use the configured Secure Search engine. Resolution: This behavior is as designed. Manually set McAfee Secure Search as the default search provider.
1110634		10.5.0	As Designed	Issue: When a deployment task for ENS fails because of an insufficient version of McAfee Agent, the McAfee Agent Monitor displays a message that says the task is successful. Resolution: This behavior is as designed. Ending the deployment process during the prerequisite software check is not considered a failure state by McAfee Agent. The deployment does not continue to the download phase. As far as McAfee Agent is concerned, the task itself was successful in running, even though it ended prematurely. This behavior is different from when the deployment fails while running the installation program after it has been downloaded to the endpoint.
1109943		10.5.0	Will Not Fix	Issue: TIE Module (TIEm) for VirusScan Enterprise (VSE) 1.0 incorrectly displays as installed alongside ENS. Resolution: This issue will not be resolved. Remove the registry key that causes McAfee Agent to report that TIEm for VSE is still installed: Make sure that TIEm for VSE 1.0 files are not present on the endpoint. Remove the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ Network Associates\ePolicy Orchestrator\Application Plugins\JTIC____1000].
1099253		10.5.0	Will Not Fix	Issue: ENS fails to preserve custom settings for features that are not installed in VirusScan Enterprise 8.8 when you upgrade to ENS 10.5. Resolution: This issue will not be resolved.
1097395			Will Not Fix	Issue: The Action Taken properties from "Contains pattern" values in the Threat Event Log, show Intrusion Detection System (IDS) strings, for example, “IDS_ALERT_ACT_TAK_DEN”. These strings are instead of natural language strings, for example, “deny access”. Resolution: This issue will not be resolved.
1094383		10.5.0	Will Not Fix	Issue: The VirusScan Enterprise Buffer Overflow Protection (BOP) exclusion API value is not migrated if either the module or API name contains a period (for example, dll.socket or fakeAPI.abc). Resolution: This issue will not be resolved. Make sure that the module or API name does not contain a period.
1089748		10.5.0	Will Not Fix	Issue: Sometimes there is a delay in the display of the email annotation in Outlook. Resolution: This issue will not be resolved.
1086074	KB86948	10.5.0	Will Not Fix	Issue: On Windows Server operating systems, the Internet Explorer browser setting Enable third-party browser extensions is disabled by default. ENS Web Control requires this option to be enabled. After ENS Web Control is installed, the user can't enable the setting Enable third-party browser extensions. Resolution: This issue will not be resolved. Enable the setting Enable third-party browser extensions in Internet Explorer. See the related article for more information.
1083135		10.5.0	As Designed	Issue: The list of assigned tasks in one group is not moved to another group when a major upgrade is deployed from ePolicy Orchestrator (for example, ENS 10.5 to 10.6). Resolution: This behavior is as designed.
1075106		10.5.0	Will Not Fix	Issue: Firewall DNS blocking is not enforced for Internet Explorer running on Windows 7 64-bit, and Windows Server 2008 R2 systems. Resolution: This issue will not be resolved. This issue is intermittent and occurs only for a short time after you upgrade ENS.
1074557		10.5.0	Will Not Fix	Issue: The McTray icon is distorted after you install ENS in a TPS environment. Resolution: This issue will not be resolved.
1070400		10.5.0	As Designed	Issue: The client UI does not start in Safe Mode. Resolution: This behavior is as designed.
1070739		10.5.0	Will Not Fix	Issue: Natural language descriptions are not properly translated. Resolution: This issue will not be resolved. To resolve the issue, restart the system.
1057970	KB84522	10.5.0	Will Not Fix	Issue: The service start process times out while waiting for a dependent service to start. If the service does not respond in 30 seconds, Windows stops the service. Resolution: This issue will not be resolved. Log on and start the service manually from the Services user interface (Services.MSC). The service also starts automatically from a COM ping when a browser window is left open for a few minutes. See the related article for more information.
1070189		10.5.0	Will Not Fix	Issue: Even if you choose another language for the client interface language, the interface language of ENS Web Control is written in the default language. Resolution: This issue will not be resolved. The language of the ENS Web Control interface in the browser does not depend on the client user interface language that is set. The language is localized based on system locale.
996973		10.5.0	As Designed	Issue: A manual installation generates an Unidentified Publisher error. Resolution: This behavior is as designed. Check Event Viewer, Windows Logs, Application log for the latest event from source Certificate Services Client to verify that it has been started successfully. Certificate Services Client is a core part of Windows that manages certificate handling, such as certificate enrollment, including auto-enrollment and credential roaming.
996375		10.5.0	As Designed	Issue: A Windows Security Audit failure occurs because of mfeelamk.sys. Resolution: This behavior is as designed. A driver developed for Windows 8 and signed by "Microsoft Windows Early Launch Anti-malware Publisher" is generating audit errors on Windows 7. Depending on how often your system is designed to run an audit, you might see several of these errors in the Windows Event Log.
993212		10.5.0	As Designed	Issue: ENS client help is not enabled for screen readers, such as JAWS. Resolution: This behavior is not supported.
991842		10.5.0	As Designed	Issue: By default, Use system proxy settings is selected in the Common setting for a self-managed system. Resolution: This behavior is as designed. Use the local UI to change the setting.
990974		10.5.0	As Designed	Issue: Some informational common settings for modules still exist in the Common settings page even though the module is not installed. For example, Threat Prevention events are not removed after the related blades are uninstalled from the system. Resolution: This behavior is as designed. No problems occur because of the existence of these settings.
990805		10.5.0	Will Not Fix	Issue: The local update task does not run at the specified time, but instead runs later. Resolution: This issue will not be resolved. To avoid a network storm, the local update task uses a randomization of 60 minutes when setting up the schedule. So, the update task runs within 60 minutes of the scheduled time. The randomization setting is not available from the local UI and can't be changed.
982238		10.5.0	As Designed	Issue: A sharing violation error is logged in the local log file after scanning the C:\Windows folder. The sharing violation is expected because of the files being open exclusively (no shared read) in Windows processes. Resolution: This behavior is as designed. The sharing violation error severity is set to Informational, which means by default the error is not sent to ePolicy Orchestrator. Also, the error does not display in the Windows Event Log by default.
976918		10.5.0	As Designed	Issue: Some Access Protection rules protect against remote access, such as the Remotely accessing local files or folders rule. When these rules are enabled and an access is reported or blocked, the target path value in the Event Log might report the pipe connection. It can report the pipe connection rather than the file path that was requested in the access that was tried. For example, the Event Log might report \\.\pipe\srvsvc rather than \\computer\share\filename. Resolution: This behavior is as designed, and is a reflection of how the Windows file system works.
949580		10.5.0	As Designed	Issue: An erroneous summary is displayed in the Threat Summary: Threat free for last 30 days if ENS was installed in the last 30 days. Resolution: This behavior is as designed. If there have been no threats in the last 30 days, ENS displays this message. If there were threats in the last 30 days, ENS displays the exact number of threat-free days.
922465		10.5.0	As Designed	Issue: The Firewall Rules table does not allow a new rule to be added to a new empty group in one step. Resolution: This behavior is as designed. To move a newly added firewall rule to an empty group, first drag the rule above the group, and then drag and drop the rule inside the new group.
919855		10.5.0	As Designed	Issue: When running some ePolicy Orchestrator ENS event queries, and you drill down on a specific event's details, not all details of the event display. Resolution: This behavior is as designed. Select the Go to related Event Log link to see the complete event details.
912588		10.5.0	As Designed	Issue: There are no Self-Protection events in the Windows Event Viewer, the ENS Client Event Viewer, or ePolicy Orchestrator Threat Events. Resolution: This behavior is as designed. Self-Protection events are set to Informational by default and they are tied to the Event Filtering of Access-Protection. All event filtering is set to Major and Critical by default in ePolicy Orchestrator and in the client UI. To see Self-Protection events in the Windows Event Viewer, the ENS Client Event Viewer, or ePolicy Orchestrator Threat Events, you must change the Event Filtering for Access-Protection to All. Because All includes informational events, Self-Protection events display in the three areas mentioned. NOTE: Regardless of the Event Filtering settings, Self-Protection events are logged to the SelfProtection_Activity.log file located in %PROGRAMDAT%\McAfee\Endpoint or %allusersprofile%\application data\McAfee\Endpoint. You can view this information at any point if needed.
898131		10.5.0	Will Not Fix	Issue: Clicking Update Now reports a successful update when the system is already up to date. Resolution: This issue will not be resolved. When you click Update Now, the updater is initiated and the repository is checked for new updates. This behavior occurs regardless of whether the system is already up to date. Even in the case where no update is applied, the updater reports that the update was successful.

1247352 1251563 1251979 1252011	KB90848	10.5.4 August Update	10.5.4 September Update	Issue: A blue screen error with bug check SYSTEM_SERVICE_EXCEPTION (3b) can occur after installing ENS 10.5.4 August Update. Because of this issue, McAfee has removed ENS 10.5.4 August Update from the Product Downloads site. For those customers that have already downloaded ENS 10.5.4 August Update, McAfee recommends to not install this update. Resolution: This issue is resolved in ENS 10.5.4 September Update. See the related article for more information.
1235182		10.5.4	10.6.0	Issue: A JavaScript error displays when trying to create an Expert Rule, when using Internet Explorer. Workaround: Use a different browser, such as Mozilla Firefox or Google Chrome. Resolution: This issue is resolved in ENS 10.6.0.
1230704	KB90510	10.5.3	10.6.0	Issue: A Product Deployment for Threat Prevention never expires and remains showing the status Running on the Product Deployment page in ePolicy Orchestrator. The Completion rate shows 0%. But, the endpoint received the Product Deployment task and installed the managed product successfully. Resolution: This issue is resolved in ENS 10.6.0. See the related article for more information.
1227138 1231176		10.5.3	10.6.0	Issue: In the Threat Prevention policy (as viewed through ePolicy Orchestrator and the local ENS console), Options, Proactive Data Analysis, there are two options: McAfee GTI Feedback and Safety Pulse. These options are interdependent; but, disabling McAfee GTI Feedback does not necessarily disable the Safety Pulse option. Workaround: To disable both options, you must disable Safety Pulse before you disable McAfee GTI Feedback because disabling McAfee GTI Feedback immediately hides the checkbox for Safety Pulse. Resolution: This issue is resolved in ENS 10.5.4 June Update and ENS 10.6.0.
1220432	KB89771	10.5.3	10.5.3 Hotfix 1	Issue: A rare system crash (blue screen error) with bug check 133 involving the mfefirek.sys firewall driver can be encountered on high-demand server class systems.

1219240 1217114	KB90053	10.5.3 (GA)	10.5.3 (Repost)	Issue: Under a specific and rare race condition, a system crash (blue screen error) might occur during an upgrade from an earlier (older) ENS version to ENS 10.5.3. Workaround: If a system has encountered this issue and does not automatically restart, see the related article for the workaround procedure. Resolution: The repost of ENS 10.5.3 corrects this issue. See the related article for more information. If you currently have ENS 10.5.3 installed, you can continue to run ENS 10.5.3 on the system because the issue occurs only during the initial upgrade. For any new installations of ENS 10.5.3, we recommend that you use the ENS 10.5.3 repost.
1213473		10.5.3	10.6.0	Issue: In the ENS About box, the Real Protect engine content version 1.0.0.2817 displays with a date of 1/31/2017. The correct date is 8/14/2017. Resolution: This issue is resolved in ENS 10.6.0.
1211101	KB89985	10.5.3	10.5.3	Issue: On 64-bit systems, upgrades from previous versions of ENS that were installed by explicitly providing the custom installation path "c:\Program Files (x86)\" do not update the ENS Platform files. Workaround: Uninstall ENS from the custom installation path and then install the latest version of ENS. Resolution: This issue is resolved in ENS 10.5.3. But, this issue could not be fixed for systems that are already installed and upgrading from ENS 10.5.2 or earlier. Only a clean installation of ENS 10.5.3 will address the issue and prevent it from happening in the future. See the related article for more information.
1206158	KB89681	10.5.1 Hotfix 2	10.5.2	Issue: Services that are needed for ENS functionality fail to load on Windows 7 Embedded systems when ENS 10.5.1 Hotfix 2 is applied to the system. Resolution: This issue is resolved in ENS 10.5.2. See the related article for more information.
1191601	KB89864	10.5.1	10.5.3	Issue: When ENS Exploit Prevention policies are backed up or exported, the backup copy contains only the Exploit Prevention content signatures from the content version when the backup was created. When the backup policy is restored on an ePolicy Orchestrator server with newer ENS Exploit Prevention content, the imported policy is missing any new content signatures until the next Exploit Prevention content update. Workaround: Workaround steps are outlined in the related article. Resolution: This issue is resolved in ENS 10.5.3.
1179148		10.5.1	10.5.3	Issue: The Access Protection rule "Changing any file extension registrations" is not effective at preventing changing file extension registrations. Resolution: This issue is resolved in ENS 10.5.3.
1211550 1182188	KB89855 KB89904	10.5.1	10.5.3 10.5.2 Hotfix 1213762	Issue: After Exploit Prevention content is updated, the Application Protection Rules policies are set back to the default configuration. This set back means that any previously configured user-defined rules (also called custom rules) must be re-created. Resolution: This issue is resolved in ENS 10.5.2 Threat Prevention extension Hotfix 1213762 and ENS 10.5.3. See the related articles for more information.
1184551		10.5.1	10.5.3	Issue: AMCore content is not retained on client systems after upgrading ENS. Resolution: This issue is resolved in ENS 10.5.3.
	KB89029	10.5.1	10.5.1 Hotfix 1	Issue: If Device Guard or Credential Guard is enabled on a Windows 10 Creators Update 64-bit system, you must make sure that Microsoft KB4016251 is installed on the system before you install McAfee products. For more information, see KB89029. Because of an issue in Windows 10 Creators Update, if Microsoft KB4016251 is not installed and you install McAfee products, the system experiences a system crash (blue screen error) and is no longer bootable. Currently, there is no known workaround for this issue. Resolution: The issue does not occur if you install ENS 10.5.1 with Hotfix 1 on the Windows 10 Creators Update system. See the related article for more information.
1235700 1235504 1235375 1166985	KB90480	10.5.0	10.5.3	Issue: Systems might experience a random system crash (blue screen error) with bug check 7E when Threat Prevention 10.5.0, 10.5.1, or 10.5.2 is installed.

1186563		10.5.0	10.5.1	Issue: After the ENS Exploit Prevention content is updated, some systems might not display new or updated content signatures in the Endpoint Security Threat Prevention - Exploit Prevention policy, or when the standalone client is used. Resolution: This issue is resolved in ENS 10.5.1.
1182777	KB88815	10.5.0	Microsoft fix available	Issue: After Threat Prevention is installed, Windows Server 2012 or Windows Server 2012 R2 servers with Cluster Shared Volumes randomly experience a system crash (blue screen error). Workaround: The issue does not occur with Windows Server 2016. Resolution: There is a Microsoft release that resolves this issue, which is described in the March 2017 rollup: https://support.microsoft.com/en-us/help/4012219/march-2017-preview-of-monthly-quality-rollup-for-windows-8-1-and-windows-server-2012-r2. See the related article for more information.
1176129		10.5.0	10.5.1	Issue: The firewall is unable to communicate with the Global Threat Intelligence (GTI) server through a proxy. Resolution: This issue is resolved in ENS 10.5.1.
1172948 1173107		10.5.0	10.5.1	Issue: The firewall blocks all traffic if the Global Threat Intelligence (GTI) server is unavailable. Resolution: This issue is resolved in ENS 10.5.1. Traffic is no longer blocked if ENS is unable to access the GTI server.
1164824		10.5.0	10.5.3	Issue: If you edit the block or report settings for an Exploit Prevention signature, the client UI might display that signature at the bottom of the list of signatures. This display might happen even though the list is sorted numerically otherwise. Workaround: In the client UI, scroll to the bottom of the list of Exploit Prevention signatures to find signatures whose block or report settings have been changed from their default value. Resolution: This issue is resolved in ENS 10.5.3.
1163245		10.5.0	10.5.3	Issue: When ENS is installed, it creates the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\RealProtect" for the Real Protect component. Uninstallation of ENS does not delete this registry key. This registry key is a subkey of "HKEY_LOCAL_MACHINE\SOFTWARE\McAfee" so it does not interfere with any other products. Workaround: Manually delete the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\RealProtect". Resolution: This issue is resolved in ENS 10.5.3.
1137347		10.5.0	10.5.3	Issue: An upgrade of the TIE for VirusScan Enterprise extension to TIE for Endpoint Security did not update the event descriptions. The upgraded extension is still able to manage clients with Threat Intelligence Exchange for VirusScan Enterprise. Resolution: This issue is resolved in ENS 10.5.3.

Resolution: This issue is resolved in ENS 10.5.2.
1179065		10.5.1	10.5.2	Issue: A system crash (blue screen error) occurs after restarting a system when ENS is installed with some McAfee products. These products include VirusScan Enterprise, Host Intrusion Prevention, Data Loss Prevention, and Drive Encryption with File and Removable Media Protection (FRP). Cause: The kernel is running out of stack space during a file operation because there are more than the usual number of filters on the file stack. This fact causes a CPU double fault and the blue screen error. FRP currently uses the minimum kernel stack needed for a call, which is 4 K. Workaround: Increase this stack size as suggested below: Start the system in Windows Safe Mode. Navigate to the registry location HKLM/System/CurrentControlSet/Services/mfeeeff. Create a DWORD value with the name MinKernelStack and set it to 16384. Resolution: This issue is resolved in ENS 10.5.2.
1223054	KB90150	10.5.0	Citrix PVS 7.6	Issue: A system crash (blue screen) occurs after you successfully install or upgrade to ENS 10.5.x (and later) or VirusScan Enterprise 8.8 Patch 10 (and later). After a system restart, the computer enters a reboot cycle after it shows a system crash (blue screen) with the following crash details: Bug check 7E Error: Stop: 0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF8800217F198, 0xFFFFF880009A8F68, 0xFFFFF880009A87D0) CLASSPNP.SYS - Address FFFFF8800217F198 base at FFFFF8800217E000, DateStamp 4ce7929b MER mfeclnk.sys The issue is seen on Citrix XenApp clients running the Citrix File System Minifilter PVS driver.

1183713		10.5.0	10.5.1 Hotfix 2	Issue: There is high CPU usage by mfetp.exe during policy enforcement when ENS writes On-Access Scan exclusions into the registry. Workaround: Limit the number of On-Access Scan exclusions in the policy. Resolution: This issue is resolved in ENS 10.5.1 Hotfix 2.
1182181	KB88866	10.5.0	10.5.1	Issue: In ePolicy Orchestrator, when the total number of characters in the path for the On-Access Scan exclusions plus the internal separators exceeds 5000, the policy does not enforce on the end node.

1172855		10.5.0	10.5.1	Issue: Automatic Migration fails for edited VirusScan Enterprise My Default Policies for on-demand scan when the Both Workstation and Server settings migration option is selected. After the Automatic Migration "MyDefault 2" policies are created twice, one each for workstation and server-specific policies. This action then causes the policy migration to Threat Prevention to fail. Workaround: In the policy preview page, manually rename the Threat Prevention on-demand scan policy that has the duplicate name to a unique name. Resolution: This issue is resolved in ENS 10.5.1.
1171976		10.5.0	10.5.1	Issue: When you upgrade an endpoint with ENS 10.5 installed from Windows 7 x64 to Windows 10 x64, Exploit Prevention fails to initialize and remains disabled. Cause: A race condition between mfetp and the VSCore driver, ESP, or MA Service during the installation flow causes this issue. This race condition leaves the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ services\mfeepmpk\Enum set to 1 by mistake, and indicates a failure during initialization. The result is that Exploit Prevention remains disabled and can't be initialized. Workaround: To avoid the issue, perform the following steps: Before you start the Windows 10 upgrade process, disable ENS Self-Protection. Press Windows+R, type regedit, and click OK. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ services\mfeepmpk\Enum Set INITSTARTFAILED to 0. Enable ENS Self-Protection. Start the Windows 10 upgrade process.

The detect gateway options can be organization default gateway, web gateway enforcement, or internal landmark. Workaround: Do not select multiple detect gateway options, select one of the options that best suits the environment. Resolution: This issue is resolved in ENS 10.5.1.
1164347		10.5.0	10.5.1	Issue: In the Host Intrusion Prevention catalog network, you add an IP address with a fully qualified domain name without a dot. After migration to the ENS Catalog, if you try to open the migrated catalog in ENS, an unexpected error appears. (For example, a name without a dot is Google.) Workaround: Before migration, delete all networks in the Host Intrusion Prevention catalog without a dot. Resolution: This issue is resolved in ENS 10.5.1.
1164345		10.5.0	10.5.1	Issue: An exception error displays when you open an ENS firewall rule for editing in the Rules policy migrated from Host Intrusion Prevention. And, the same rule from the same Host Intrusion Prevention Rule policy is open in another tab. Workaround: To compare the migrated Host Intrusion Prevention rule and the original Host Intrusion Prevention rule, use the rule summary or open rules in different browsers. Resolution: This issue is resolved in ENS 10.5.1.

The list includes an ENS Firewall policy that was migrated from Host IPS using the Migration Assistant. If you change the object in the Host IPS catalog, the ENS Firewall policy becomes corrupted. Resolution: This issue is resolved in Host IPS 8.0 Update 11. If you already encountered the issue, remigrate the ENS Firewall policy after modifying the object in the Host IPS Catalog.
1204316		10.5.0	10.5.3	Issue: An AMCore content update succeeded, but the AMCore content version is not shown in the ENS Console or ePolicy Orchestrator. The correct AMCore content version is shown in the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\AVSolution\DS\DS]. The ThreatPrevention_Debug.log shows the following error: 07/13/2017 11:22:36.916 AM mfetp(4472.4508) AvContentMgr.AVCMGR.Error: Failed to load container: Failed to load xml document, 0x00000001 Resolution: This issue is resolved in ENS 10.5.3.
1186400	KB89023	10.5.0	10.5.3	Issue: If Threat Prevention Exploit Prevention is enabled, the dllhost.exe process will generate a crash dump after it performs a Cortana search on a Windows 10 Creators Update system. The issue occurs when Exploit Prevention fails to inject into the dllhost.exe process; the result is the process does not load and generates a crash dump.

See the related article for more information. Resolution: This issue is resolved in ENS 10.5.3.
1181041	KB88793	10.5.0	10.5.1 Hotfix 1	Issue: A Location Aware Group (LAG) with a local network and with connection isolation enabled blocks traffic by isolation. The issue occurs when the address specified in the local network of the LAG does not match an active network adapter on the system. Workaround: Reconfigure the LAG without a local network as a location criteria; use other location criteria that is suitable in the environment. Resolution: This issue is resolved in ENS 10.5.1 Hotfix 1. See the related article for more information.
1177881 1175503		10.5.0	10.5.1	Issue: Clients do not send metadata, such as file names, to the Threat Intelligence Exchange server when the option Allow the Threat Intelligence Exchange server to collect anonymous diagnostic and usage data is disabled. Resolution: This issue is resolved in ENS 10.5.1. The option Allow the Threat Intelligence Exchange server to collect anonymous diagnostic and usage data now applies only to optional statistics collection by clients. Metadata is sent to the Threat Intelligence Exchange server.
1172168	KB88198	10.5.0	10.5.1	Issue: When ENS Web Control enforces an action in the browser, an enforcement message is displayed in the browser.

1148888		10.5.0	10.5.1	Issue: Packages created with ENS Package Designer do not honor the license type, which causes the ePolicy Orchestrator server to always display the package as Licensed. This issue does not impact the licensed General Availability (GA) packages being customized. It impacts only the ENS evaluation builds when used to create custom packages. There is no functional impact on the client. The client About dialog box still displays it as Trial only. Only the ePolicy Orchestrator Master Repository displays as Licensed for trial packages. Resolution: This issue is resolved in ENS 10.5.1.
1139050	KB87511	10.5.0	10.5.1	Issue: After you upgrade ENS, permission set data is not retained accurately for the Firewall extension, if it had two categories of permissions sets before the upgrade.
