I never use IE yet it keeps coming up with that URL over and over. I've run AdAware, Spybot, Avast, and nothing has helped.

You've been infected with a browser hijacker. You could try and remove it with Malwarebytes Anti-Malware, be sure to uncheck the trial offer when installing it and then run a full scan.

If it doesn't work you could try and reset Internet Explorer to do this:

Close all Internet Explorer and Explorer windows that are currently open.

Start Internet Explorer, on the Tools menu, tap or click Internet options. If you don't see the Tools menu, press Alt.

In the Internet Options window, tap or click the Advanced tab.
Tap or click Reset. If you're using Windows Internet Explorer 6, click Restore Default.
