k, farbar gave me some output now, but of course i'm having more issues
combofix didn't produce a log - either in c:/, or on the desktop where the executable's located.
i did, however, have to download combofix twice and the second time it saved as ComboFix(1).exe. I ran the executable under that name, it scanned fine but afterwards i got an error saying "you cannot rename ComboFix as CombiFix(1)" and it renamed itself back to ComboFix. i don't know if that had anything to do with the log?
