This article describes how to manually remove VSE 8.8 if automatic removal is not an option or fails.

IMPORTANT: Use the following instructions only as a last resort for removing VirusScan Enterprise 8.8. Before attempting a manual removal, try all other methods first.

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, McAfee strongly recommends backing up your registry and understanding 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.

Solution 1

Use msiexec.exe to remove remnants (if Add/Remove Programs is unavailable)
Sometimes you can remove VSE remnants using msiexec.exe with the product installation string. This can save time and McAfee recommends that you use this method before you try to manually remove VSE .
