Hey Jak123 I'm in the same boat, someone downloaded AV 2009 and some other stuff on the work pc. I removed the programs to no avail and if i try to do a windows search for more file the pc reboots, my google page looks funny and i can't go to norton or other antivirus websites or do live update on a newly installed norton antivirus.
i wanted to ask did you disable system restore before you went through your procedures?
