If a virus, worm, or Trojan infects a computer, System Restore may back up that virus, worm, or Trojan. Windows XP does not allow outside programs (including anti-virus utilities) to alter files in the System Restore folder. Therefore, virus removal tools cannot remove security threats found within this folder. An infected file within the System Restore folder could potentially be restored onto your computer. Also, virus scans may detect these infected files even after you have removed the threat from your machine.
For these reasons, when applying a virus removal tool, Windows XP users should temporarily turn off the System Restore feature. This will allow the removal tool to delete any infected files in the System Restore folder as well. Instructions are provided below.
Turning System Restore On or Off on Windows XP
When you turn off the System Restore feature, you will not remove or delete any personal files from your computer. Only those files that were created by System Restore are removed. Likewise, if you use the System Restore feature to "restore" back to a previous state, personal files in your My Documents folder are not affected.
Note: You must be logged in as an Administrator. If not, the System Restore tab will not display.
To turn off System Restore:
1. Click Start > All Programs > Accessories > Windows Explorer.
2. Right-click My Computer and select Properties.
3. Select the System Restore tab.
4. Select (check) the Turn off System Restore option.
You can choose to exclude any non-system partition or drive so that System Restore does not monitor or restore it. Changes made on an excluded partition or drive are not restored during a System Restore.
Restart your virus scan now and quarantine any suspect files, repair or delete those not needed by your OS. Make sure to turn ON system restore once the PC's repaired.
Hope this helps!

Did you run your antivirus program in Safe Mode? Some viruses are self executable and simply revive themselves; and, sometimes when not in Safe Mode, they are not caught.
Just a thought.
