Malwarebytes – the most trusted free malware scanner for macOS.

macOS has solid built-in protection, but it does not catch everything. Malwarebytes fills that gap. It scans your Mac for malware, adware, and spyware that slipped through — and removes them cleanly. The free version does not run in the background, but as an on-demand scanner it is one of the best tools available for Mac.

Key Features:

• Malware Scanner: Detects and removes malware, adware, spyware, and potentially unwanted programs.
• Fast Scans: Runs a full system scan in under two minutes on most Macs.
• Clean Removal: Removes threats completely, including files left behind after deletion.
• Simple Interface: One button to scan, one button to remove — no technical knowledge needed.
• Premium Option: Upgrade to real-time protection that blocks threats before they reach your Mac.
• Trusted: Used by over 500 million people worldwide across Mac and other platforms.
