Corrupt CFW blocking Internet access

Had power outage. Suddenly CFW gone from tray, Internet Access blocked. Reset. Message:

Comodo Firewall 10
Comodo Security Agent could not be started. Would you like to run the diagniostics tool to fix this error?

Fix not possible. Tried uninstalling. Blue Screen of Death. Tried restoring to a previous restore point. No restore points to restore. Tried Safe Mode. Internet worked. Found article about a group-developed uninstaller. Looks like it doesn´t do V10.
Unchecked Comodo Driver in Network Properties. That worked. Have Internet access back. But above message keeps coming back, for Comodo is still there. So simple question: how do I completely remove CFW without using the WIndows Uninstaller (which doesn´t work).

PS An running Win10
