Click this link to get to the homepage, http://www.yahoo.com
While on the homepage, click Tools, click Internet Options.
Then if there is something else in the box, back space it out and type the link in.
Also you can click "Use Current" click Apply and ok. Restart the computer.
There is no telling what this could be, with everything going on with Yahoo these days.
You can clear the browser cache of cookies, temp files and history, click Ok and Restart the computer to see if it clears it.
