How to reset the security centre manually in XP or VIsta:
1. Go to control panel and open Administrative tools.
2. Click on services.
3. Go down to Windows Management Instrumentation.
4. Stop this service. Stop Security Center service too.
Set them to Automatically start.
5. Exit out of this area, to your desktop.
6. Right click Start, and choose Explore.
7. Go to c:\windows\system32\wbem\repository.
Delete this subdirectory ONLY. (repository).
Leave the others there.
8. Exit back to your desktop and reboot your computer (you might need to boot twice).
This will rebuild the deleted folder, and the database.
Once restarted, Windows Security Center should show the correct info.
Antivirus, and firewall, should now be recognized.
All steps are important. It should be straightforward, if you are using an admin account. You will probably have to ‘ok’ your way through a UAC warning message or two.
The above is pretty much the same procedure as DavidR posted in his first link, above, I think.
