Kick hackers to the curb
Malwarebytes for Windows Premium is a comprehensive cybersecurity program that crushes established and emerging threats before they can disrupt your digital lifestyle. So you can play, shop, and socialize online with peace of mind.
What it does for you
Protects you from emerging 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 technology that works proactively to shield your files. This is a powerful, complete defense that blocks ransomware, and not a simple decryption tool.
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 websites used by scammers 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 download a video. It's done by the time you're ready to watch.
Crushes the latest scams
Detects and blocks phishing scams used to steal your identity or hack your banking account. Stops cryptojacking (malicious cryptomining) software that hackers install on your computer to “mine” for cryptocurrency (bitcoin and others) without your knowledge.
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.
