https://forums.comodo.com/help_for_v...-t17220.0.html

If there is still a reference to Comodo Firewall in Windows Security Center:

At a Command Prompt, type

"NET STOP WINMGMT /Y" (without the quotes; there must be a space between WINMGMT and /Y) and press Enter. Then type "exit" end press Enter again.
Go to the folder C:\WINDOWS\system32\wbem and delete the folder "Repository".
Reboot. The Repository folder will be recreated automatically by the Security Center and will now display the correct information.

Ba-da-bing!
