We are very excited to announce the release of Malwarebytes Anti-Ransomware beta!

As mentioned in the blog announcement by Marcin this beta is extremely exciting as it introduces the most innovative approach in the market today for protecting against ransomware; 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.


Installation is very straight forward. Simply download and install from the link below. You can safely install Malwarebytes Anti-Ransomware beta alongside Malwarebytes Anti-Malware and Malwarebytes Anti-Exploit. If you encounter a problem or false positive please read this.

Download link (beta8 - build

VERY IMPORTANT!!:  Please note that you must first uninstall any earlier BETA versions prior to installing BETA 8.  You will not see an upgrade notice in product for this version.


Please report any issues you might find in this forum. Both Nathan Scott, aka Decrypterfixer, our resident ransomware researcher and Technical Product Manager of Anti-Ransomware, and myself, will be happy to help out with any feedback.


Malwarebytes Anti-Ransomware BETA collects certain data to ensure optimal product functionality and performance.

  • Version of the software installed including specific product, build, and version number so we can determine correct version of product installed and apply updates as appropriate.
  • License details so that we know if it’s an older version of the beta and should be expired.
  • General system info such as OS, system language, processor and file system in use to understand how the product behaves in different environments.
  • Data on any potentially malicious activity including a copy of the executable file that caused the program to alert, along with internal product logs which include information on the detection logic so that we can improve the product’s efficacy.

Please see the Malwarebytes Anti-Ransomware BETA EULA and the Software Collection Addendum in the Malwarebytes Privacy Policy for more detail.

Thanks for participating in this beta program and helping us improve this exciting technology that makes up Malwarebytes Anti-Ransomware!

Hi all, as Pedro said, we are very excited about this beta. A few common questions came up and so I'll link a few of Pedro's answers that were scattered around the forums.


I have MBAM and MBAE. Why do I need Anti-Ransomware?


How do I report a False Positive?


Also, as many of you guessed, this will not be a standalone product/agent but rather rolled into our existing products.

Beta 6, v., is now available via link above.  

This is only available for new downloads to start, but we'll enable upgrades for current users later this week.  If you're running an earlier beta, you can always download and install Beta 6 on top of your current version.

  Change Log for Malwarebytes Anti-Ransomware (BETA)

Known Issues:

•   Protection will be disabled after upgrading to Beta 6, v. 0.9.15.  Simply click Start Protection or Fix Now to re-enable protection.  (This issue is fixed in Beta 6, but you won’t see it working as expected until the next upgrade to Beta 7.)

•   If installing the upgrade on Windows 8.1 x64 over a previous Beta, the service may not start automatically.  In this case, simply click Start Protection on the Malwarebytes Anti-Ransomware dashboard or run the Beta installer a second time.


•   Further refinements to internal rules to reduce false positives

•   Refactored processing to reduce memory consumption and prevent system hangs

•   Added ability to update internal rules dynamically without requiring a full program update so new detections and fixes for false positives can be deployed much more rapidly

•   Changed log collection to happen asynchronously

Issues Fixed:

•   Notification that a new version is available no longer auto-dismisses

•   Fixed issue where an Exclusion may not have been honored properly in some cases

 program update

•   Fixed issue where the protection status was not remembered correctly after a program update (will see this work correctly as of next beta...)
