Cannot Install or Uninstall an Anti-Virus in Windows Security Center
*Cannot install or uninstall an anti-virus entry in Windows Security Center*
So until the offending antivirus or Firewall entry is removed from the root\securitycenter WMI namespace, the user won’t be able to install an antivirus.
TO RESOLVE THIS PROBLEM:
Click on Start menu > Run > type in:
wbemtest
Click OK
Connect to root\SecurityCenter
You would need to change the root\default to root\securitycenter
Click on Query tab
Type in SELECT * FROM AntivirusProduct
Click on Apply
In the Query result window, highlight the offending antivirus and click Delete.
