I didn't read all the posts but if you do do all that then you can just reinstall your os. ie game over thanks for playing. There are a few programs out there for free that can help ya out alot. 1. Ad-aware @ http://www.lavasoftusa.com/ 2. A pop-up stopper (I use popup popper @ http://www.bayden.com/popper/) google has a tool bar that also blocks pop-ups 3. Virus scanner (I use the avg free version @ http://www.grisoft.com/us/us_index.php) 4. A good personal firewall system (zone alarm) I don't use, as I am behind a hardware/software firewall. All of the above can help!!!
