The problem I'm having is on both my Desktop and Laptop PC's. Every time I open Firefox, I get a "Domain Name Mismatch" popup, asking me to accept the certificate to Microsoft Forums. Two popups, saying the same thing, occur every couple of minutes. I've run AVG Antispyware, AVG Antivirus, and cleared out all my temp files. Here is my log.
