Have you done a total virus scan & checked with -ad-ware: http://www.lavasoftusa.com/software/adaware/ & -Spy Sweeper: http://www.webroot.com/wb/downloads/index.php Did you see the link I left in my last post? It's about somebody who had the same problem. Which AV softw do you use. I have links to online checks if you're interested (Norton, etc.)? These will check your comp whilst you'e online.
