I shall use ComboFix

In addition to singing and painting pictures for a living, I also fix computers. My worlds end up colliding quite a bit. Yesterday, for example, I made a ComboFix logo linocut so that I could apply ComboFix to things other than infected Windows computers

ComboFix, incidentally, is a fierce, awe-some, and scary program. Don't run it. I'm even kind of wary of using this stamp on things. Ha!
