Malwarebytes is a next-generation antivirus replacement. The first of its kind for home users, Malwarebytes employs four independent technology modules—anti-malware, anti-ransomware, anti-exploit, and malicious website protection—to block and remove both known and unknown threats.

Windows Version

Crushes advanced malware before it crushes you

Anti-malware defense deploys heuristics and behavioral analysis to protect you and your online experience. Detects and removes malware in real-time with advanced anti-malware, anti-spyware, and anti-rootkit technology. Scans for the newest and most dangerous threats automatically, so you’re protected without having to even think about it.

Protects you from having to pay ransom for your files

Stops unknown and known ransomware with proprietary next-gen technology that works proactively to shield your files. This is a powerful, comprehensive defense that blocks ransomware, and not a simple decryption tool. So you’re protected from tomorrow’s “Ransomware Attack!” headlines today.

Prevents your programs from being used against you

Advanced anti-exploit defenses intercept and block exploits that use bugs in popular software programs to compromise your computer. Wraps your browser and software programs in four layers of defense, stopping attacks that use vulnerabilities in those programs to infect your computer.

Protects you from fake and infected websites

Detects and prevents contact with fake websites and malicious links. You are proactively protected from downloading malware, hacking attempts, and infected advertising. Worried about wandering into a “bad” Internet neighborhood? Now you don’t have to be.

Scans faster, scans smarter

Lightning-fast Hyper Scan mode targets only the threats that are currently active. Faster analysis. Still gets results. Run a scan in the background while you boot up your favorite game. It's done by the time you're ready to play.

Mac Version

Protects you from Mac threats

Detects and removes viruses, ransomware, and other malware in real time with advanced anti-malware technology. Catches dangerous threats automatically, so you’re protected without having to even think about it.

Scans Mac-fast

Scans the average Mac in under 30 seconds. Run the malware scanner in the background while you boot up your favorite game and it's done by the time you're ready to play. You can even customize your scans to run when you're not using your Mac at all—at any day, at any time.

Stops unwanted apps at the source

Blocks applications from developers who are known to release unwanted software like malware, PUPs, or adware. App Block outsmarts developers who try to bypass security by releasing a slightly different version of their app.

Removes adware and unwanted programs

Crushes adware and potentially unwanted programs that slow your Mac. Your Mac experience will remain clean and pristine.

Light and lean

Only the size of three digital music files. That means more disk space for your movies, music, and apps.

Android Version

Detects ransomware before it can lock your device

Real-time protection shields your device from infection. With mobile malware threats on the rise, advanced technologies deal with dangerous newcomers like ransomware before they can become a problem.

Safer browsing experience

Scans for phishing URLs when you're using the Chrome browser and alerts you when any are detected to ensure you have a safer experience while surfing the web. (Only available for phones and tablets).

Conducts privacy audit for all apps

Identifies the access privileges of every app on your Android device so you know exactly what information you're sharing. Keep tabs on which apps can track your location, monitor your calls, or cost you extra in hidden fees.

Finds and removes adware and malware

Searches all files and apps quickly and effectively for malware or potentially unwanted programs such as screen lockers or adware, freeing your Android device from bloatware.
