Environment

McAfee Application Control (MAC) 6.1

Adobe Reader
Google Chrome
Mozilla Firefox

Summary

This article describes a behavior where Adobe Reader, Google Chrome, or Mozilla Firefox might not work as expected when MAC 6.1 is enabled.

Problem

A conflict exists between MAC 6.1 Memory Protection and sandboxing technology used by the following products:
  • Acrobat Reader - Displays an error pop-up window while opening a PDF file.
  • Chrome - Browser opens a blank page with Memory Protection (MP) enabled.
  • Firefox - Hangs when a flash-intensive site is browsed.

Solution

This issue is resolved in MAC 6.2.0 (or later).

McAfee product software, upgrades, maintenance releases, and documentation are available from the Product Downloads site at: http://www.mcafee.com/us/downloads/downloads.aspx.

NOTE: You need a valid Grant Number for access. KB56057 provides additional information about the Product Downloads site, and alternate locations for some products.

Workaround

Do the following to work around this issue for the respective browser:

For Chrome:
  1. Create a shortcut for Chrome.
  2. Right-click the new shortcut and click Properties.
  3. Add the following to the target entry: -no-sandbox
  4. Use this shortcut to launch Chrome.
Or:
  1. Click Start, Run, type cmd, and click OK.
  2. Run the following command:  chrome.exe –no-sandbox  
For Adobe:
CAUTION: This article contains information about opening or modifying the registry.
  • The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
  • Before proceeding, Technical Support strongly recommends that you back up your registry and understand the restore process. For more information, see: http://support.microsoft.com/kb/256986.
  • Do not run a REG file that is not confirmed to be a genuine registry import file.
  1. Click Start, Run, type regedit, and click OK.
  2. Navigate to: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Reader\11.0\FeatureLockDown\bProtectedMode]
  3. Change the registry value to 0.

For Firefox: Disable Protected Mode:
  1. Click Start, Run, type explorer, and click OK
  2. Navigate to the mms.cfg file located in:

    • Windows (32-bit): C:\windows\system32\macromed\flash
    • Windows (64-bit): C:\windows\syswow64\macromed\flash
       
  3. Add the following line to the mms.cfg file:

    ProtectedMode=0
     
  4. Save the changes.

Workaround

If the first workaround does not help, bypass the process for Adobe and Chrome from MP-CASP and MP-VASR. 

If you want to bypass the process(es) from MP, contact Technical Support.
