Disabling System Restore
Windows ME and XP utilize a restore utility that backs up selected files automatically to the C:\_Restore folder. This means that an infected file could be stored there as a backup file, and VirusScan will be unable to delete these files. You must disable the System Restore Utility to remove the infected files from the C:\_Restore folder.
