NOTE:  Removing System Restore is the LAST step in your cleaning procedure.  Continuing with this procedure will DELETE ALL your system restore points, infected or not.  It is best to read this article explaining System Restore before following the instructions below.

Before doing this make sure your computer reboots.  Try to make sure your system is clean of viruses except in system restore.  Do NOT follow these directions if you have NOT tried to restore to an earlier time before you were infected.  An infected restore point is better than none at all.  But once you have a clean machine, the following procedure is the ONLY way I know of to clean your restore points because they are protected files.  

No matter what your software says it is doing it cannot clean your restore points.

WARNING:  This will DELETE ALL your system restore points


Disable System Restore:
Click Start, right-click My Computer, and then click Properties.
