       It seems the information I found on this worm is that it 
probably hides in the "system volume information" folder that is 
"read only" and "hidden" by default. The worm just keeps getting 
reinstalled and can't be cleaned unless the permissions are 
changed for that folder. The information on this site links to 
instructions for cleaning RAMNIT.A.

      This links to information on how to disable "system 
restore" in order to remove the infection. It may be possible to 
use some offline scanner like BitDefender to remove the worm but 
it's better done in Windows.
