About Malwarebytes
Protection that works when people need it most
Malwarebytes began after founder Marcin Kleczynski accidentally infected his parents' computer while downloading a video game as a teenager. At the time, there was no product that could fully solve the problem, so he set out to build one. Since then, the digital threat landscape has only grown more complex; Malwarebytes believes protection should be both powerful and refreshingly simple, and aims to stay one step ahead by cutting through the noise, stopping threats others miss, and delivering peace of mind in an unpredictable digital world.
