Try Mcafee Viruscan9 and Webroot Spysweeper,.........I had a bunch of nasty stuff and the apps you mentioned didn't help at all,.......a friend told me about the 2 apps I mentioned(both have limited time free trial versions), and things are running smoothly ever since. Might not work for you, just sharing my experience.
