is bringing cyberprotection to every one.

Our Story

We believe that when you’re free from threats, you’re free to thrive.

Here at Malwarebytes, we believe that when you’re free from threats, you’re free to thrive. It all started with one person who needed help with a malware infection, and a community coming together to find solutions. In that moment in time a product was born for all people, with a mission to rid the world of malware.

Our product has since grown and evolved. From removing malware, to protecting devices, to ever-changing prevention.

Now we’re doing so much more than just malware remediation. We’ve forged ahead into the world of cyberprotection, privacy, and beyond.

Our products are robust, and our tech effective, across devices and the cloud. We’re trusted by businesses large and small, and institutions like schools, hospitals and governments. We’re powered by AI, and behavioral-based technology, and driven by hundreds of researchers, hunters, and innovators. All committed to delivering the best cyberprotection available anywhere.

We’re relentlessly committed to bringing effective, intuitive, and inclusive solutions.

We’re intuitive to use, and we’re more accessible to more people from all walks of life, from grandparents to geeks.

Malwarebytes is at home in the home, on-the-go, and in the corporate conference room. Made for individuals, public organizations, private entities, and everything in between.

This is what we live for, and we’re relentlessly committed to bringing effective, intuitive, and inclusive solutions to the people, families, and businesses of all kinds.
