Well there is some reason for that problem.
So lets do some steps to get it to run which should uncover that reason.
-------------------------------------------------------------------------------------------------------------------------------------
Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "Cleanup at TechSpot".
Then
Start-Programs-Accessories-System Tools-Disk Cleanup
Click OK to accept C:
Select all Boxes
Then click More Options
Here click System Restore and OK to "Are you sure" and the OK to Run.
As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.
It clears what is known as Shadow copies which are used by specialized back up programs.
Since you had Malware in System Volume Information (System Restore) and Shadow copies this needed to be done any way.
This is if you have the Volume Shadow Copy running which is the default.

D/L install and run ATF-Cleaner clear all except passwords in all browsers you have. Run repeatedly until no more found.
