There are several different steps needed to completely remove MacKeeper from your Mac. These are:
Now we will address each of the steps in detail to make it clearer how to free your Mac of MacKeeper.
Clicking on the menu bar illustrates one of the ways in which MacKeeper makes itself difficult to remove or even stop running. There’s no Quit command. And it doesn’t want you to Force Quit either. So, to delete MacKeeper from your Mac’s menu bar you need to:
Uninstall MacKeeper
~/Library/Application Support/MacKeeper Helper (this one is a folder, delete the whole folder)
/Caches/com.mackeeper.MacKeeper
/Caches/com.mackeeper.MacKeeper.Helper
/LaunchAgents/com.mackeeper.MacKeeper.Helper.plist
/Application Support/MacKeeper Helper
/LaunchDaemons/com.mackeeper.MacKeeper.plugin.AntiTheft.daemon.plist
Finally, Empty the Trash and reboot.
