Malwarebytes Anti-Malware

Malwarebytes was founded in 2008 by Marcin Kleczynski and Bruce Harrison as a specialized solution for detecting and removing malicious software that traditional antivirus programs often missed. The software quickly gained a reputation for its powerful scanning engine and efficiency in cleaning compromised systems.

Today, the brand remains a private entity headquartered in Santa Clara, California. While the software is distributed globally via digital downloads, its core research, development, and primary operations are centered in the United States and Ireland. The brand has expanded from a simple clean-up tool into a comprehensive security suite for both home users and large-scale enterprises.

Malwarebytes continues to operate as an independent company, backed by significant investments from private equity firms such as Fidelity Management and Research Company. It maintains subsidiaries in various regions, including Malwarebytes Ltd in Estonia and Ireland, to manage international distribution and specialized data research operations.
