Malwarebytes for Mac: Free Malware and Adware Removal (How to Use It)
Macs are safer than they used to be, but they're not immune. Adware that hijacks your browser, fake 'cleaner' apps and info-stealers disguised as downloads are all very real on macOS.
Malwarebytes for Mac has a free scanner that finds and removes that kind of thing. It's a great second opinion when your Mac starts acting strangely.
What is Malwarebytes for Mac?
Malwarebytes for Mac is a malware scanner from Malwarebytes. The free version scans your Mac on demand and removes adware, potentially unwanted programs, browser hijackers and malware. The paid Premium version adds real-time protection that blocks threats before they run. New installs may start a Premium trial, which drops back to the free scanner when it ends.

FAQ
Do Macs need antivirus?
macOS has good built-in protection, and for many people that's enough. A free scanner like Malwarebytes is a useful extra check, especially for adware.
Does the free version protect me all the time?
No. The free version only scans when you ask it to. Real-time protection is part of the paid Premium version.
The verdict
Your Mac's built-in protection does a lot, but it's not perfect. Keep Malwarebytes installed and run a free scan whenever something feels off.
