The System Volume Information folder is used by Windows XP for storing data on system configuration and is also used by the System Restore tool to store information and restore points.
Restore points allows you to return to the previous configuration that preceded the installation of a driver or program.

Normally the access to the System Volume Information folder is locked, but a virus can work around that.
The unlock procedure varies depending on the version of Windows XP used, disk format or network configuration.
As an example, here is the path of a virus found in the System Volume Information folder:
C:\System Volume Information\_restore{4E170950-50E0-453F-B281-59338F8EC32E}\RP16\A0003104.exe
Cleaning up the System Volume Information from viruses:
Right click on My Computer select the Properties Option.
Go to the System Restore sub menu.
Deactivate the Turn off System Restore on all drives and validate by clicking on the Ok button.

A message will inform the removal of all existing restore points.
Confirm with “Yes“.
Reactivate the Turn off System Restore on all drives option and create a new restore point.
Your problem should be over.
Thank you for the great and easy solution to solve the problem. I’ll use it to get some win32.induc.a-virusses from my computer, but is there a way to prevent the virus from working around the locked folder? (some kind of lock on the door)
