I'm not sure if this is virus/trojan related or not, but when I go to web pages with small embedded visual advertisements, the ads will display correctly for a second and then be replaced with a server error message the page cannot be displayed. I should mention if I quickly right click on the advertisements and look at their properties, they will be pointing to a standard ad server like doubleclick. However if I right click on the advertisement after the Server Error message is displayed. The properties now point to something like res://E:\WINDOWS\system32\shdoclc.dll/http_400.htm# http://www.inonto.com/728x90.aspx . Avast and Ad aware scans find no viruses, but other computer in my house do not have this strange behavior, which only started a few days ago. Something seems to be redirecting the ads.
