Announcing Malwarebytes 3
Malwarebytes is a next-generation antivirus replacement. Malwarebytes is the first of its kind for home users, employing four independent technology modules—anti-malware, anti-ransomware, anti-exploit, and malicious website protection—to block and remove both known and unknown threats.
Full protection or simple disinfection?
Download Malwarebytes for Windows for free and you get 14 days of full real-time protection. After the 14 days are up, Malwarebytes for Windows reverts to a very limited but still free version that will only disinfect your computer after an attack. We recommend the full real-time protection of Malwarebytes for Windows Premium to prevent infection in the first place.

Take a look inside
What it does for you
Protects you from advanced threats
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 your files from being locked and held for ransom
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
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.
Don't take our word for it
Had a nasty malware infection, I tried everything out there and was about to give up. [Then I] tried Malwarebytes as a last resort. Reboot—problem solved! Worth every penny.
I bought the Premium...I totally recommend this. You will use it every day, and with peace of mind, no matter what other security you have on your computer.
