I tried clearing the cache and tried the link to see what the hosts file looks like, looks ok after copying and pasting commands to see if there was any extra stuff, and there wasn't. I tried the norton power eraser tool and found 3 suspicious files and after checking with symantac servers, they were not bad. I don't know what else to try.

I solved it!!! After reading posts from other people with similiar problems, do the following: go to control panel then add/remove programs look for the program called "Anti Phishing Domain Advisor" click remove to uninstall it try the link in your browser with the problem

I didn't think it would be there but it was. Now I can get into my yahoo mail with the link for it. Let me know if this works for you.
