Just commenting here to say I agree, this is definitely not intuitively worded. I was about the uninstall Malwarebytes I was growing so irritated with the useless notifications that it had done nothing, and I had already been through that section of the UI.
The button is written to make it sound like it should be unchecked if you don't want to be notified that Malwarebytes has done nothing. It's also very well hidden, you already have a spot for notifications in settings so it seems logical that notifcation options would be... in notification options.
