Forums ask for login for chamillionaire.com constantly?

[WesternZypher]

I've checked my PC for spyware and the like, haven't found anything. Other sites run fine; also using Avast!.

Whenever I reload a forums page inside of ocremix.org, I get asked for a login and password for chamillionaire.com. Anyone else seeing this?

Whenever this happens, it's usually somebody's sig that had an old image in it, and the status of the site it's from had changed. I deleted Al Capwn's sig.
