Error 404 Spyware Page

When I go to a website that does not exist in IE a page comes up saying Error 404 and it has links to different internet categories and such. How do I get this to go back to the original IE page not found page instead of this one and Ive run alot of spyware programs. Here is my Hijack This log. Hope it helps.
