Malwarebytes 4 is smarter, faster, and lighter than ever before. Our new Malwarebytes Katana detection engine finds more threats, in less time, with less performance impact. It also tells you more about threats it finds, like their type and behavior, so you can make smarter security decisions. Go beyond antivirus and stop worrying about online threats.

What Malwarebytes 4 does for you:

Cleans your PC in just a few minutes. Our free scanner is what put us on the map. It doesn’t just find threats like malware and viruses, it also finds potentially unwanted programs that can slow you down.

Secures your PC, files, and privacy 24/7. Real-Time Protection uses artificial intelligence and machine learning to keep you safe from online threats, even emerging threats that no one has ever seen before.

Protects against online scammers. Web Protection blocks online scams, infected sites, and malicious links. It also blocks phishing scams, which use fake sites to trick you into revealing private info like your bank details.

Stops your files from being held for ransom. 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. 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. 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.

For real-time protection that actively prevents infections and protects against malware, viruses, adware, spyware, Trojans and other threats, including blocking unwanted programs, Malwarebytes offers a 14-day free trial of its Malwarebytes Premium software. Basic free version of the software offers manual scanning and removes infections after an attack.
