Good luck. I run Ewido, AVG, Defender, Adaware, Spybot with Tea Timer resident and also run trend online. Still get fooled every once in a while by BHO's and add-ons. I also run Tweaknow Reg Cleaner. My Internet Explorer homepage is blank. After using it to surf I hit the home page, clear everything and exit. Then I run Disk Cleaner just to make sure. Smitrem is also a regular as I once had spyaxe.

I generally browse with Opera and use IE only when I have to.
