If you are using the full version of Ad Aware, have you made sure that the Ad Watch part of the program loads when Windows Starts, as this should prevent Spyware from getting inside your computer?
Combine the above with Windows Defender and very little if anything will get through. (Make sure you update Ad Aware regularly)
