Overview

Malwarebytes is a cybersecurity company based in Santa Clara, California. Its official site describes all-in-one cybersecurity that protects users from malware, viruses, scams, and other online threats, spanning device security, online privacy, and identity protection. The company states it was founded by Marcin Kleczynski, who wrote the first iteration of the code and, seventeen years after its founding, is still leading the company. It describes itself as a global leader in online protection with offices and remote employees across the United States and the world.

History

Malwarebytes was founded by Marcin Kleczynski, who wrote the first iteration of the code. According to the company, like many teenagers in the early 2000s, Marcin downloaded files from a file sharing site and discovered that the family computer was infected with a virus. With the help of an online forum community, he created the first version of the Malwarebytes software to safely scrub the virus from his computer and help others in a similar situation. That community shaped the founding of the company. Since then, Malwarebytes has evolved from a device cleaner to proactive malware monitoring and web traffic protection, to providing safety and peace of mind beyond devices with identity protection tools. Seventeen years after its founding, Marcin Kleczynski is still leading the company.
