Malwarebytes Security Software

Malwarebytes was founded in 2008 by Marcin Kleczynski and Bruce Harrison. The brand is originally from the United States, starting as a small project to create a tool capable of removing persistent malware that other programs missed. It grew into a globally recognized cybersecurity platform protecting millions of home and business users.

While software development and core engineering take place in the United States, Malwarebytes operates and maintains a global presence with offices in several countries. The brand remains privately held, headquartered in Santa Clara, California. It has received significant investment from private equity firms such as Thoma Bravo and Vector Capital to expand its product offerings and global reach.

The service is available across multiple platforms, including Windows, macOS, Android, and iOS. It has evolved from a simple removal tool into a comprehensive security suite that includes real-time protection, web monitoring, and VPN services, maintaining its independence under its parent corporation, Malwarebytes Inc.
