Kept getting multiple popups from Malwarebytes trying to get me to subscribe to a paid service. Finally the addon interfered with my email and ability to get online. I tried to uninstall the Malwarbytes software but kept getting 'wait for other program to uninstall' message. But I wasn't trying to uninstall any other program. Finally after opening in safe mode - the computer very sluggish the entire time - I was able to uninstall. After rebooting a couple of times in normal mode things finally got back to normal. Whether a but or a deliberate attempt to compel purchase, this program is terrible. Does it make your computer safer? I don't know, but if the computer won't run, what's the difference?
