Stops ransomware

Stops ransomware

Ransomware Protection uses proprietary tech to create a powerful defense against malware that locks down your PC and takes your files and photos hostage.

Respects your space

Respects your space

Scans now use 50 percent less CPU resources than before, and with Play Mode, you can even turn off notifications and updates while you game or watch movies.

Makes your security simple

Makes your security simple

Our all-new user interface makes it easier than ever to customize your protection. Schedule scans, adjust protection layers, and choose from three scan modes.

Malwarebytes Katana Engine

Our all-new detection engine finds more threats, in less time, with less performance impact than ever before. It also tells you more about threats it finds, like their type and behavior, so you can make smarter security decisions. For example, instead of seeing a generic threat name like “Malware123,” you'll see a name like “Spyware.PasswordStealer,” along with a link to information about that specific threat.

“Malwarebytes gives me a sense of protection and lets me stay confident that my systems are being kept safe. I can even relax about my kids surfing habits knowing we have a solid layer of security keeping an eye on things.”

‒ Brian H

“Honestly, it is the first antivirus that I have ever used that has given me full peace of mind. I had tried so many others and had never felt compelled to purchase the product beyond the trial until I heard of Malwarebytes through a friend.”

‒ Torjus H

“The main thing is that I can be sure that by installing Malwarebytes on friends' and families' devices I don't need to constantly fix their malware-problems.”
