What's the best to to completely uninstall?

I want to do a complete uninstall of an old version, I’m talking not a single COMODO registry / file left afterwards. Is there a way to do this?

I’ve been trying to completely remove comodo from my computer for four years. I still haven’t figured it out.

Comodo never starts up correctly at bootup. I always have to manually start it up.
