Cannot delete icon on menu bar

Solution 1:

Only first-party menu bar apps can be ⌘-dragged off the menu bar. To remove third-party menu bar apps, you should refer to the specific app settings. For Malwarebytes, you can turn off the menu bar app from Malwarebytes preferences → Hide application icon. To properly uninstall Malwarebytes if you no longer want the software, open Malwarebytes, and go to "help" > "uninstall Malwarebytes".

Solution 2:

If you moved to trash for deleting the app and the icon is still sticked in menu bar;

Go to > Activity Monitor -> Search for FrontendAgent and double click on it click Open Files and Ports tab.

You ll see the Malwarebytes source path like /Library/Application Support/Malwarebytes/ Open the terminal:

sudo rm -rf /Library/Application\ Support/Malwarebytes/ replace this path with have you seen in Activity monitor screen if not the same one and run the command.

Then Quit the job from activity monitor.

Thats all.
