I've been nailed with several nasty trojans lately myself, and I haven't been anywhere I shouldn't have.... ~_~
Firefox and IE both love to randomly crash heavily on VGChartz is all I know for sure. And I mean "program disappears, no crash warning or anything of the sort" type of problem.
Then again, Backdoor.SdBot3.RJU was messing hell with me until I upgraded to a new protection software, so a new windows install may be heading in my near future... damnit!
Nobody is crazy enough to accuse me of being sane.
