Virus MS AntiSpyware 2009

Question

1. Repeatedly (even after rebooting several times) a popup alert window ''Windows Security Center'' comes up telling me I do not have the MS AntiSpyware 2009. It seems this is attacking everything and I cannot do anything - to include going online.

2. The Alert from MS AntiSpyware 2009 says my computer is being attacked by several viruses. The question then comes up asking if I want MS AntiSpyware 2009 to block the attack. I have McAfee Firewall installed and operating and Norton Security installed and operating.

3. HELP!
