Built and beloved by experts

Seventeen years after its founding, the same person that wrote the first iteration of code, Marcin Kleczynski, is still leading 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 and continues to be a driving force today. 

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. 
 

Now a global leader in online protection, our suite of award-winning cybersecurity and privacy solutions empower millions of people worldwide to enjoy their digital lives, free from threats and scams. 

Based in Santa Clara, California, Malwarebytes has offices and (remote) employees all over the United States and the world.
