Webroot ran clean, Spyzooka found:

Still, it seems like a spyzooka download was the source of the w32 nonsense.
p.s. had a blue screen of death which said to run diagnositcs and suggested memory or sound card. That's interesting, since I was having that volume mute issue and I have had two strange incidents one of high cpu and one high memory. I hope to determine what the problem is before ordering memory, so I don't waste my money if I need a new system...
Dang computers!
