See the Related Information section below for contact details.
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.
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.
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 required 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.
Issue: When installing ENS 10.7.0 using the standalone installer, and supplying the verbose logging switch (for example, "setupEP.exe ADDLOCAL="tp,atp,fw" /l*v"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.
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, ensure 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 upgrading 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.
Issue: After switching between ENS Firewall and Host IPS Firewall, WSC incorrectly reports the status of ENS Firewall and Host IPS Firewall. For example, after you disable Host IPS Firewall and enable ENS Firewall, WSC reports the status of ENS Firewall as disabled.
Resolution: The product functionality is not affected for either ENS Firewall or Host IPS Firewall. McAfee is working toward a fix that is expected to be available in early Q1 2020. See the related article for more information.
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.
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 and ENS 10.6.1 December 2019 Update. The fix for ENS 10.7.0 will be included in the next release. See the related article for more information.
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.
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.
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.
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 required. The Second Attempted Action is Block and correctly blocks the activity.
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
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 protectionsection of Windows Defender Security Center after you upgrade to ENS 10.5.5 from an older version.
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 will be 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.
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 ensure 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.
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.
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.
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.
1234588
10.6.0
As Designed
Issue: PowerShell script invocation can enter a hung state on Windows Server 2016 after installing ENS Threat Prevention 10.6.x.
Cause: ENS 10.6.x supports Antimalware Scan Interface (AMSI) and PowerShell script invocation is subjected to AMSI examination. This issue occurs when ENS is not the only AMSI provider on a Windows Server 2016 system. The ENS 10.6.x installation does not remove Windows Defender on Windows Server 2016 (see known issue 1149046). This fact results in both ENS and Windows Defender being active AMSI providers and causes AMSI to malfunction.
Resolution: This behavior is as designed. Perform the following steps:
Use the following PowerShell command to manually uninstall Windows Defender before installing ENS:
Make sure that the following AMSI registry keys do not have the Windows Defender GUID {2781761E-28E0-4109-99FE-B9D127C57AFE} registered. The Windows Defender uninstall does not automatically perform this cleanup.
Confirm that Windows Defender is not active using the following command:
sc query Windefend

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.
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
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.
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.
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.
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.
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.
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, ensure that there is a copy of AMCore content in both of the branches. See the related article for more information.
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.

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.

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.
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.

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.

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 required 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, ensure that any current work is saved, and close running desktop programs. The user can likely see that the Endpoint Security Platform uninstallation is occurring.

Issue: ENS does not disable Windows Defender on Windows Server 2016. Microsoft has deprecated the Windows API to enable or disable Windows Defender in Windows Server 2016. This fact could lead to performance issues, but this issue has not been confirmed. The best practice is to run a single real-time antivirus solution.
Resolution: This behavior is as designed. Use PowerShell to manually disable Windows Defender:
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.
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.

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.

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.

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.
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.

Issue: BugCheck KMODE_EXCEPTION_NOT_HANDLED (1e) occurs. This issue is typically found on Windows 10 kernels, such as Windows Server 2016, and the process is typically the cluster service clussvc.exe. Disabling Real Protect might resolve the issue. The stack text is similar to the following:
Issue: Microsoft Internet Explorer, Outlook, or Word hangs or crashes when Exploit Prevention is enabled, and you open a document from SharePoint or off a network share in the presence of Microsoft Application Virtualization.
Workaround: Perform one of the following workarounds:
Create an Application Protection Rule exclusion for the affected application.
Make Signature 6015 a Repot only event.
Add an "Illegal API User – Buffer Overflow" signature exclusion for the affected application where the Caller Module is appventsubsystems32.dll, the Signature is 6015, and the API is LoadLibraryW.

10.5.3
10.5.4
Issue: If an ePolicy Orchestrator (ePO) repository branch contains many previous ENS updates and hotfixes, checking in the 10.5.3 update into the same repository branch might result in ePO becoming unresponsive.
Workaround: To prevent the issue, remove all updates and hotfixes except for the previous version, before checking in the 10.5.3 update. If you already encountered this issue and ePO is unresponsive, stop and restart the ePO service to resolve the issue.
Issue: After you disable Access Protection via policy in ePolicy Orchestrator (ePO), once enforced on the client, the ENS console still shows that Access Protection is enabled. This information is then reported incorrectly back to ePO. This issue is cosmetic. When the policy is enforced, Access Protection is successfully disabled on the client.
Resolution: This issue is resolved in ENS 10.5.3 Hotfix 1. See the related article for more information.

10.5.3
10.5.4
Issue: An upgrade to ENS 10.5.3 fails if Threat Intelligence Exchange (TIE) Client 10.2 is installed. This result is an intermittent issue.
Cause: There is a timing issue. The TIE Client tries to validate the installer utility before it is written to disk. This fact causes the McAfee trust verifier to treat the installer utility as untrusted.
Workaround: Perform one of the following options:
Attempt to send another deployment task to the systems with this issue. The chance of the upgrade succeeding in the second attempt is higher.
Uninstall TIE Client 10.2 before upgrading to a later version or update. The deployment task for 10.5.x must include the Adaptive Threat Protection module to match the parity with TIE Client 10.2.x.
Resolution: This issue is resolved in ENS 10.5.4.

Issue: When the Firewall Options policy Allow bridged traffic option is enabled and you apply the policy to a virtual machine, Firewall rules are not enforced and traffic to and from the virtual machine is allowed.
Resolution: This issue is resolved in ENS 10.5.3 Hotfix 3 and ENS 10.5.4.
Issue: When you select the "Configure different settings for High Risk and Low Risk processes" option in the On-Access Scan policy, and all High Risk processes are removed, the High Risk processes are still enforced.
Workaround: Ensure that there is at least one High Risk process in the policy.
Resolution: This issue is resolved in ENS 10.5.4. See the related article for more information.
10.5.2
10.5.3
Issue: When performing a right-click on-demand scan for a network share, the scan completes in seconds and 0 files were scanned. This issue happens even though you are logged on to the client system, with credentials that have local administrator rights to the network share.
Issue: During an installation or upgrade to ENS 10.5.2, an error occurs during the installation process that causes an MSI pop-up error. Installation is successful, but systems occasionally get the following pop-up error:
Error 1336. There was an error creating a temporary file that is needed to complete this installation. Folder: C:\Program Files\McAfee\
Endpoint Security\Threat Prevention. System error code: 5.
Workaround: Use the following steps to work around this issue. See the related article for more information.
Disable ENS Self-Protection. From the local console, navigate to Settings, Common, and disable Self-protection.
Issue: When you install ENS using a custom policy that specifies a custom quarantine path, the quarantine is created in the default folder C:\Quarantine instead of the specified custom path.
Workaround: For ePO managed systems, the quarantine folder is automatically reset to the custom path specified in the policy on the next policy enforcement. Either wait for the next policy enforcement to occur, or manually trigger policy enforcement using one of the options in the related article.
Resolution: This issue is resolved in ENS 10.5.4.

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 required 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.
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:
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.
Resolution: Upgrade Citrix PVS to version 7.6 or later before you install or upgrade your ENS or VirusScan Enterprise installation. See the related article for more information.
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.
Resolution: This issue is resolved in ENS 10.5.1. See the related article for more information.

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.

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.

Issue: When you edit an object in the Host Intrusion Prevention (Host IPS) catalog, a list displays with all affected policies that the change will propagate to. 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.

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
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.
Workaround: Add a global Exploit Prevention exclusion for the dllhost.exe process. The exclusion stops injection from being performed on the dllhost.exe process, and crash dumps are not generated. See the related article for more information.
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.

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.
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. These two categories are, Endpoint Security Firewall Catalog and Client and Endpoint Security Firewall.
Workaround: Run the SQL script attached in the related article on the ePolicy Orchestrator server after you upgrade ENS to restore the Firewall extension permission set data.
Resolution: This issue is resolved in ENS 10.5.1. See the related article for more information.

Issue: There are compatibility issues with ENS and Entrust 9.3, including the following:
Performance issues
After installation of ENS on a system with Entrust 9.3, the system will not start after a restart.

Issue: After you install ENS on a Windows 7 system with Forcepoint (formerly Websense) Data Loss Prevention (DLP) 7.8 installed, a system crash (blue screen error) occurs.
Workaround: Either remove the Forcepoint software or upgrade to Windows 10.
Resolution: McAfee has determined that the cause of this issue is the Forcepoint software that uses the QIP.sys driver on Windows 7 systems. Any solution must come from Forcepoint. If you experience this issue, McAfee recommends that you contact Forcepoint Technical Support for assistance. This issue has not been reported to occur with newer versions of Forcepoint DLP 8.2. See the related article for more information.
Issue: Installation of ENS fails when Entrust Entelligence 9.2 is installed.
Resolution: Upgrade to Entrust Entelligence 9.3. Installations of ENS are successful with the latest Entrust Entelligence version. See the related article for more information.
