Windows Security Centre can't locate my firewall or antivirus software

Windows Security Centre can't locate my firewall or antivirus software for some reason, all of a sudden.

I use Zonealarm Free and AVG Free Edition respectively, what have they done to offend Security Centre?

hi, i found the avg issue on others pc's running avg and xp, never seemed to cause a problem though, avg still worked
never come across the zone alarm one, but if the icon is active in your system tray, then you should be ok

Did you have any other anti-virus/firewall beofre you installed Zonealarm and AVG?

No, I didn't. The three things have been playing nicely for a very long time.
