damn, i hope you figure it out, i know my little problem a while back took a long time to figure out
i'd definitely try it without the overclock tho.. my at7-max2+2400 will NOT run stable at even a single clock over default bus (although it will run fine at either 133 or 166). usually tho, it won't even start up... bsod's on its way into windows.
as far as spyware goes, you may try several variants. adaware is very good, but not definitive by itself. i usually run adaware and swatit, but i know there are others out there that are very good for this. keep ad aware, but run 1 or two others, may be interesting what you find.
