Malwarebytes has stopped working

Recommended Posts

Just updated to version Pro and program hangs on startup.  Was working fine before update.  Used removal tool, re-downloaded program from your site, reinstalled, activated and have same issue if trying to update database (v2014.03.04.09 is current one) or perform scan.  Use Norton Internet Securoty and have exluded Malwarebytes folder from scan. Dowloaded and ran tests with suggested programs (FRST64.exe and mbam-check- and am attaching required files for inspection.  Would appreciate your help in getting Malwarebytes up and running properly again.  Thanks.

Hi,RobK, and :welcome:


Before we go any further, first of all, can you tell me if by


...and have same issue if trying to update database (v2014.03.04.09 is current one) or perform scan.


Do you mean that it hangs or that it crashes (as you said it was hanging on startup initially)?


The reason I ask is that if it is a crash, then we're going to take a totally different route than the diagnostics above, but I want to be sure before we side track as to the exact nature of the problem.

The program will load to the main dasboard screen.  If I click on update database, it starts its process and then a "stopped working" dialog box pops up.  The same occurs if I try to perform a scan.  Also performed a rootkill and this is the result:

That's what I needed to know, the 'stopped working ' part.


OK, time for the side track.


First, ( but only if the program is running) let's shutdown the realtime Malwarebytes Anti-Malware. Go to the desktop Taskbar. See the blue-color MBAM icon in the notification area.

Do a Right-click on it with your mouse, and select EXIT.
{ if you are only running the Free mode program, you will not see that, so in that case you can ignore that step.}.

Download & Save to your system a zip file named REF_Replace.zip from this link https://malwarebytes...33c7kcqxnpp8ldc

Once saved, unzip **REF_Replace.zip**  to extract all contents.   which will be 4 files.
Next, double-click on **Ref-Replace.bat** file.
It should run fairly quickly in a command-prompt window.

I would suggest then a Logoff >> Shutdown >> Restart so that your pc is then in a new Windows session.

Once that is done, restart the Anti-Malware and let me know if it works normally.

OK, Maurice is giving me the go ahead to get some more info and such.


Do you have a 3rd party firewall running, or else have any other AntiMalware programs on your system that run as well as MBAM?


Also, Just to reiterate, you did use the actual MBAM 2 Clean Removal Tool to uninstall MBAM and then downloaded the latest version directly from the website here and installed it, instead of installing an older version and updating it, right?

I'm sorry but the logs indicate that you're stealing software from Adobe. As such we cannot provide further assistance. I will close your topic for now. If you wish to remove the Adobe software and the hack we will go ahead and assist you, just send me a private message letting me know this topic link and that you've removed the software in question.




This topic will now be closed due to evidence of cracked or pirated software on this system.

Thank you

Topic has been reopened as user says they have removed all illegal software from the system.


Please restart the computer 2 times. Then run a new scan for FRST and make sure to check the ADDITIONS.TXT check box to get a new log for that as well. Then also run the MBAM CHECK scanner and post back all 3 new logs.

I see no button or prompt to attach requested files.  Do you want the text files copied and pasted?
