In case a virus is detected by the AVG program on an important system file, it is not automatically removed. This functionality has been added to prevent accidental removing of infected system files that are running the operating system.

Detection of important system file is marked as follows in scan result:
"Object is white-listed (critical/system file that should not be removed)"

Below you may find examples of important system files:

  • "%WINDOWS%\system32\winlogon.exe"
  • "%WINDOWS%\system32\user32.dll"
  • "%WINDOWS%\explorer.exe"

Note: %Windows% variable usually stands for C:\Windows folder.

In case there is a virus detected in a system file, please restore the infected file from the system back-up. More information on how to restore the operating system to a previous state can be found in Microsoft’s knowledge base at:
