you can try to uninstall using Device Manager.
Go to Hardware and Sound Control Panel > Device Manager.
Next, click View menu then select "Show hidden devices"
Expand "Non-plug and play devices"
Locate the comodo driver you want to remove.
Right-click to uninstall.
I only installed the CIS firewall and not the other features on my pc. After I uninstalled it in "Programs and Features", I can't delete registry entries labeled DeviceDesc. When I go to Permission to get Full Control for Everyone, I get an error message, "Unable to save permission changes on 0000. Access is denied". I attempted to delete the entries in Safe Mode too, but I received the same error message.
