I've look over my log but i cant seem to find any obvious sign of infestation. All my running processes appear to be clean and most everything else looks normal, but im still getting pop ups and random programs are download from IE(which sucks) and messing up the computer even more. Here's my HJT log see if you can tell wats wrong.
