malware bytes good or bad on Mac

Is is good for its' intended usage

The The Built in Security  is all that is required to protect the computer.

Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac. 

It is free or paid for added features. 

Run the Application and it should remove the malware / adware. Once done, restart computer and test.

Hi,

Good. It is widely accepted as safe to use on a Mac. Other malware apps install things on your Mac and slow things down and may interfere with proper operation, but Malwarebytes does not do any of those things. I use the free version and just manually scan periodically. Very easy and fast. It's the only malware app I've ever used.
