NOTE: If W32.Klez.gen@mm was activated before you ran the removal tool, in most cases you will not be able to start Norton AntiVirus (NAV). The instructions for running NAV from the command line and NAV reinstallation instructions are in the removal section of the W32.Klez.E@mm writeup.
When the tool has finished running, you will see a message that indicates whether the computer was infected by W32.Klez.E@mm, W32.Klez.H@mm, W32.ElKern.3587, or W32.ElKern.4926. If an infection was removed, the program displays the following results:
The total number of the scanned files
The number of deleted files
The number of repaired files
The number of viral processes terminated
The number of viral services deleted
The number of registry entries fixed

System Restore option in Windows Me/XP
Windows Me and Windows XP users should temporarily turn off System Restore. This feature, which is enabled by default, is used by Windows Me/XP to restore files on your computer in case they become damaged. When a computer is infected with a virus, worm, or Trojan, it is possible that the virus, worm, or Trojan could be backed up by System Restore. By default, Windows prevents System Restore from being modified by other programs. As a result, there is the possibility that you could accidentally restore an infected file, or that online scanners would detect the threat in that location. For instructions on how to turn off System Restore, read your Windows documentation or one of the following articles:
How to disable or enable Windows Me System Restore.
How to disable or enable Windows XP System Restore.
