One thing to try is restarting in safe mode, by pressing the F8 function key
before the first Windows screen appears, and doing full, deep scans with
Microsoft antispyware until one comes through clean.
Please let us know if that does not work with this specific bug--I don't
think I have that information yet.
Additionally, it is a good idea to update your antivirus before restarting
in safe mode, and also scan with your antivirus.
