Comodo breaks everything and you can't uninstall it if you have v10 of their Firewall. Beware Comodo is well aware of this but has had over six months to come up with a fix and still nothing. If you try to uninstall it you get a BSOD. I'm desperately trying to get rid of this program. According to one tech the problem occurred when Windows upgraded to Creator's update. The uninstaller can't remove services. It throws an error and crashes the computer.
Update: Success! I found a post that said to use autoruns program by Microsoft. I was able to search for all instances of Comodo and disable them using it. I then ran the uninstaller tool that Comodo released in November. After that CCleaner to get rid of the rest of it. I'll never touch another Comodo program again.
Edit: Comodo has fixed this problem. I've gone back to it because there isn't an alternative out there comparable that is light on the resources.
Once configured correctly it becomes a firewall, Behaviour blocker and a Default/Deny all for free.
