Recurring Security Alert

This morning my computer started issuing security alerts notifying me that the firewall was off as was the malware. I turn the firewall on but under the malware section it indicates that it is reporting to the security centre in a format that is no longer supported. It also has a little Not Compatible icon to the right of the malware icon on the left. Once the firewall is turned on and the malware turns from red to yellow when we turn it on the shield in the bottom right of the screen goes yellow for a while but eventually it goes red again and I am again notified that the firewall is off and the malware is off as well.

I know my subscription is still in effect and according to the system it expires 10/03/2010.
