Antivirus 2009 Virus/Malware

Sorry I am not more savvy to tell you what this actually is. I use Mozilla Firefox as my browser. When I try to open more than one window, an AntiVirus 2009 Page opens on the second one. Now I have noticed it opening windows when i search for "Mr. Seeka", or if go to game site for another game site. I also have a Microsoft Security Sheild Alert in the startup telling me that my auto updates is not turned on. I went to my computer to activate it, but was unsuccessful. I am going to review the other forums, but any help is appreciated.

This forum helped me defeat an about.blank, I know you can help me with this as well.

 

Problem Solved indirectly by this website. Found Link to Major Geeks Forum on Downloading MalwareBytes Anti-Malware.

That kicked it's little Malware butt and the problem is gone.
