CLOSE ALL WINDOWS (even this one) AND PROGRAMS!!!!

Run Hijack This!
Click "Do a systen scan only".
Then "check" the box to the left of these item(s):

O21 - SSODL: bestreak - {874443fe-aa33-4ebf-a6ac-73208787e62d} - C:\WINDOWS\system32\viruxz.dll (file missing)

Then click "Fix checked" and close Hijack This!.

Reboot.

If you're not having any problems, that should do it.
