passing on something i got from here, check out postings dated 11/20 in this section. i had similar problem. tried al the usual run anti spyware, spybot, spysweeper, ccleaner, anti virus. not much luck until someone (Fed) said to go to control panel and open "appearances and settings" (in my case it was display; xp pro) and in the display properties click on desktop tab. then click on customize desktop. click on web and delete the "security"
