Windows Security Center not working anymore

[Guest]

Hello, suddenly the Windows Security Center does not work for me anymore. It
no longer reports that I have a virus program (and cannot recognize AVG) and
it says that Windows Defender is not working (even though it is). Have I been
compromised? Or is there just something wrong with the Security Center. I
have just disabled it because my firewall, spyware (Defender), and virus
program seem to load and work fine even though Security Center thinks
otherwise. Oh well.

Hello, suddenly the Windows Security Center does not work for me anymore.

Try this ....

Start>Run>services.msc [enter]
Scroll down to Windows Management Instrumentation and double-click it.
Now click on the "Pause" button. Leave that window open and double-click
My Computer. Navigate to %systemroot%\Windows\System32\wbem (where
%systemroot% is the drive where XP is installed). Delete the Repository
folder and *only* the Repository folder. Now go back to the WMI service
window you left open and restart the service.
This will rebuild the Repository and hopefully straighten out the
incorrect entries for all your duplicates.
In order to see the Windows files, you may need to unhide them:
Make sure you are able to see all hidden files and extensions (View tab
in Folder Options).
Check "Display the contents of system folders".
Check "Show hidden files and folders".
Uncheck "Hide protected operating system files" and click "OK" to the
dialog box.
