Nope. My guess is you have some form of spyware/malware on your computer that is hijacking your browser. I suggest that you do a full virus scan and download AdWare or Spybot to search for spyware.
Interesting. I'm using a Mac so if is spyware or malware it will be a first for me. I had a tech from Comcast out yesterday to replace my cable modem. He also ran some software of a CD he had with him. Wonder if he could have left a little "gift" behind. Or maybe some sort of DNS issue.
