First, this a long overdue thank you to those who tried to help me get the computer to stop trying to connect to a malware site.
I've been wrestling with my system ever since.
In the latest development, I can't toggle between screens (Alt-tab). Scans with NOD32, Malwarebytes and Superantispyware find nothing. However, Ad-Aware finds trojanwin32genericBT and removes it. Then the next time I scan with Ad-Aware it finds it again.
Can anyone suggest a method for permanently eliminating this nastiness (without dropping the computer off of a tall building)?
