I think I got a virus. I can get on AIM and google chrome but IE isn't working. When I click on the Icon it keeps saying internet explorer cannot display webpage when I try to go to my homepage. No other site works. I click "diagnose connection problems" and it says "www.yahoo.com is not set up to establish a connection on port World Wide Web Service (HTTP) with this computer. " under that is says "verify current proxy server configuration." I'm running vista and have a dell laptop if that helps any. Any help would be appreciated.
