The free version can be run manually by the user when desired, whereas the paid version can perform scheduled scans, automatically scan files when opened, block IP addresses of malicious web sites, and scan only those services, programs and device drivers that are currently in use.

Malwarebytes is available in both a free and a paid version.

It is available in a free version, which scans for and removes malware when started manually, and a paid version, which additionally provides scheduled scans, real-time protection and a flash-memory scanner. Made by Malwarebytes Corporation, it was first released in January 2006.
