My internet explorer won't work, help?!?

saturday my ie stopped working(i'm using ares right now) and i need help. i thought it was my isp, but that's fine because my ares did open(and i called and they said everything is good). i completely removed and reinstalled ie and even installed mozilla. but when i try to go anywhere(yahoo, google etc) the page will not load. i've run about 6 different virus scans/spyware etc and they find things, but mostly cookies. one did find a registry key that keeps coming back but it's not listed as a major problem in the scan. what can i do so my net starts working again? please help!
