a completely proactive and signature-less technology that is able to detect and block even the most dangerous of ransomware variants like CryptoWall4, CryptoLocker, Tesla, and CTB-Locker.

Malwarebytes Anti-Ransomware monitors all activity in the computer and identifies actions which are typical of ransomware activity. It keeps track of all activity and, once it has enough evidence to determine a certain process or thread to be ransomware, blocks the infection and quarantines the ransomware before it has a chance to encrypt users’ files. During development Malwarebytes Anti-Ransomware has blocked every single ransomware variant we have thrown at it. We are extremely satisfied with its results and are excited to bring this technology to our user community for further testing.

As this is the very first beta we do encourage beta users to install the product in non-production environments for testing purposes only.
