Exploit protection will not start (or starts then stops and will not restart)

[dmpuk]

When 3.1.2 starts all works and then exploit protection stops and cannot be restarted. Have tried exiting 3.1.2 but get same problem. This persists after computer reboot.

My first feeling is that you are having conflicts with McAfee Enterprise.  Please attempt to add the following exclusions to McAfee.

Files

C:\Windows\System32\drivers\mbae64.sys
C:\Windows\System32\drivers\mbam.sys
C:\Windows\System32\drivers\MBAMChameleon.sys
C:\Windows\System32\drivers\MBAMSwissArmy.sys
C:\Windows\System32\drivers\mwac.sys
C:\Windows\system32\Drivers\farflt.sys

Folders
Also the MB folder in Program Files and the one in Program Data (it is hidden by default)

C:\Program Files\Malwarebytes
C:\ProgramData\Malwarebytes

If after doing that you still have issues do a clean install of Malwarebytes.

** Download MB-Clean Here **

How to use it?

1. Download the latest version of MB-Clean by clicking the link above
2. Close all open applications
3. Double-click and run mb-clean.exe 
4. A prompt with an option to clean up the system will appear:
   • Yes - will proceed with backing up the license key (Malwarebytes 3.x only) and initiating the cleanup process
   • No - will exit the utility
5. Once the cleanup process is completed, a prompt will appear:
   • Yes – will proceed and post reboot you will be prompted to continue with the downloading, installation and activation of latest version of Malwarebytes 3.x
   • No – will exit the utility and you will not be prompted (post reboot) to download, reinstall and re-activate (not recommended)
     • We recommend rebooting immediately. Additionally, stopping at this step is not recommended and will most likely not resolve your issue(s).
6. Upon reboot, a prompt will appear:
   • Yes - will download, install and activate the latest version of Malwarebytes 3.x
   • No - will exit the utility and the cleanup process is complete
     • Choose this option if you do not want to download, install and activate the latest version of Malwarebytes 3.x
   • A log file ("mb-clean-results.txt") will be on your desktop

Thank you. Will try (though odd since McAfee has been on the machine from before MalwareBytes was ever installed).

It looks like you have a failed upgrade. Can you please download the latest MB3 installer from https://downloads.malwarebytes.com/file/mb3 and re-install over your existing installation? No need to uninstall or anything.

Thanks. Adding the exclusions made no difference so I ran the 'mb-clean' and all is well.
