I had the same problem, I would leave my machine on over night and wake up to find like 100 alerts or so. I ran Ad-aware, Spybot, CCleaner, The Cleaner, and changed my anti virus from Symantec to AVG. I also ran highjack this and ran the log through the above mentioned site (KC computers). After all that I got rid of all the alerts. The only spyware I can't get rid of yet is this stupid huntbar? Hope this helps.
