Chameleon is a program that is included with your Malwarebytes Anti-Malware Program (MBAM).


This is what Chameleon does:

  • There are certain variants of malware that are designed to stop security programs from being installed and run on infected systems.
  • Simply put, Chameleon is a tool that disguises Malwarebytes Anti-Malware (MBAM) so it can avoid the active infection that is designed to stop it, which allows MBAM to be installed and run.
  • Chameleon will also kill any known bad processes that are actively stopping MBAM from installing or running.


This is when you need to use Chameleon:

  • If MBAM will install and run without any interference from malware then there is no need to use Chameleon.
  • However, if at any time you try and install OR run MBAM but you are unable to do so, then it could be an infection preventing the installation or execution of the program. This is when Chameleon should be deployed


Chameleon will install its own driver and start to run. It will update MBAM to the latest definitions (if already installed), kill any known malicious processes that are preventing MBAM from being installed or run, then launch MBAM automatically, and a scan will begin.


You will find Chameleon in a folder of the same name within the MBAM folder.
