Systems Affected

Windows Server 2016, Windows 10 Anniversary Update and up with Device Guard, Credential Guard enabled.



Certain Malwarebytes products will not operate with some versions of Windows if either the new Device Guard or Credential Guard feature is enabled.

Device Guard and Credential Guard are meant to empower IT administrators to harden endpoint systems by only allowing certain applications to run.  The hardening process includes requiring the highest level of driver signing for applications, which is not currently supported by Malwarebytes. Instead Malwarebytes uses an alternative method allowed by Microsoft, which is very common for frequently updated applications such as security products.

This way of signing does not mean that Malwarebytes products are less secure. It simply means that we have not yet fully established to participate in the program required for Device Guard and Credential Guard.  Malwarebytes is reviewing this new program and may participate, if it does not adversely affect our ability to support customers in a timely manner.
