I have Vista Home Premium/2GB RAM/Core 2 duo

I got this security alert today when I booted. When I open Windows Security
Center it shows the problem that Windows Defender and Spyware Doctor are both
turned off. That's as it should be and as it has always been. I have
BitDefender Internet Security 2009 and it shows "No issue affects your
computer."

I used an elevated command to check that WMI and it shows as consistent. So
why did this alert suddenly start showing up?

I know I can turn the alerts off, but I'd much rather find out what caused
this problem and fix it.
