Cannot remove icon from menu bar
There is a Malwarebytes icon on the menu bar. Holding the Command key and dragging it does not work.
Also the terminal says that /home/library/applications support/ does not exist.

Proper uninstallation of Malwarebytes for Mac requires opening the Malwarebytes application and choosing Uninstall from the Help menu. If you dragged the application to the trash, you didn't uninstall it properly.
If you have deleted the application, so you can no longer open it to do the uninstall, you can use this script to do the uninstall instead:
