HOW TO DELETE COMODO FROM MAC
I had problems with this for a while and finally did some digging, and these are the steps you need to follow. Even after deleting it from my apps, I would find that Comodo was regularly running in the background and up on my menu bar. Very sneaky, and imo, devious.
1) Delete the application.
You've probably already completed this step.
2) Delete the auto-launch files.
Even though you've deleted the application (which for 99% of apps, would have been enough), there are still some files on your system that auto-launch Comodo either periodically or when you boot up your computer. There are 3 main folders you must first find to access and delete these files.
a) /Library
b) /System/Library
c) /Users/User/Library
These folders can be found easily by opening Finder then hitting Command+Shift+C to go to your computer. In each of these library folders, there will be 3 sub-folders that you must open. They are: /ApplicationSupport, /LaunchAgents, and /LaunchDaemons. In each of these folders, delete any files or folders that contain "comodo" in their name, but ONLY delete files or folders that contain "comodo" because other files listed alongside them are likely critical to proper system functionality.
3) Empty the Trash
Some of these files are likely up and running on your system since your last logon, so you may be disallowed from permanently deleting them. No problem; just restart your computer and empty the trash again. Since the files were moved to the trash, they wont auto-launch on startup and wont be running so you'll now be able to delete them.
That should do it! You may dig around and find some spare files somewhere in your system, like in your caches, but it's nothing worth wasting time in searching for or deleting (unless you want your foot as far up COMODO's *** as possible)
