Malwarebytes 2 crashes computer

Recommended Posts

I was "force" updated to 2.0.  I had reverted to 1.75 which worked fine (and the new 2.0 didn't) but eventually the update made me go to 2.0.  It stops my machine...not slows it but stops it.  I have to power down.  


Have uninstalled, run MBAM clean  Put the excludes into MS Security.  Crash.  Uninstalled both Malewarebytes and MS Security.  Repeated the clean up.  Tried Norton Security.  Put in the excludes.  Reinstalled Malewarebytes 2.0.  Crash.  


I've run the suggested logs but I've had to do so in "Safe Mode with networking" since the machine freezes if I try to run it normally.


I'd appreciate any help.  Logs attached/or copied.

Hello Mike D.:


Please attach, in your next reply to this thread, the last two minidump files that correspond to the above system crashes. Please preserve all others if needed later.


They are in the C:\WINDOWS\Minidump\ folder.


Thank you.

Hello 1PW:

Thanks for your quick reply.  The minidump folder was empty.  I checked the web on how to set windows to make the files and have NOW configured my computer to make the dump files in the event of a crash and also set on the windows error reporting service to automatic (it was set at manual).  So, when my computer crashes (which it hasn't done for some reason this morning), I'll provide the files you requested.

Hello Mike D,


Please try this one time -- a full clean removal / followed by new install of Version 2.0.2


As we go along, if something is not clear or you have some question, please ask me first.
If there is some complication, please do not do any fix by yourself.  Stop and ask me first for guidance.

Go to Control Panel >>All Control Panel items >> Programs and Features.
Locate and select Malwarebytes Anti-Malware and  (( if not there then skip this part ))   do a Right click on it and select Uninstall.
Allow the Uninstall to proceed.
Close Control Panel when done.

If the uninstall from Control Panel hiccups or does not work, please go forward and use the mbam-clean step  anyway.

Close all opened windows/apps so you will have a clear view to the desktop.
I would suggest, a new clean install as follows:
Download and SAVE  mbam-clean utility from  http://downloads.malwarebytes.org/file/mbam_clean

then run mbam-clean.exe:   Double click the "mbam-clean-" file to run the clean tool. It runs quickly.

It will ask to restart your computer, please allow it to do so very important

Next Download & SAVE  the latest version of Malwarebytes' Anti-Malware from

Run the mbam-setup.  IF your Windows is Vista / Windows 7 / 8, then do a Right-click on **mbam-setup-** and select Run as Administrator and allow to run.
Then after the setup has finished, on the Dashboard screen, press the **Update now** link.
Let me know if the update succeeds.

When all done, do a  Windows Restart.

After the successful install of Version 2.0.2, please be sure to do this.


Malwarebytes Anti-Malware works well and should run alongside antivirus software without conflicts. In some rare instances, exclusions may need to be set for your specific antivirus product to achieve the best possible system performance.
I suggest putting in trust settings in your antivirus, as follows:
Please "put as Trusted" (i.e., put Trusted application settings) for the following MBAM exe files within your Antivirus Software whitelist :

Note: If using a software firewall besides the built in "Windows Firewall" you'll need to exclude them from it as well

For 32-bit Windows Vista or Windows 7 or Windows XP:

C:\Program Files\Malwarebytes Anti-Malware\mbam.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamdor.exe
C:\Program Files\Malwarebytes Anti-Malware\mbampt.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamservice.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamscheduler.exe

For 64 bit versions of Windows Vista or Windows 7 or Windows 8:

C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamdor.exe
C:\Program Files\Malwarebytes Anti-Malware\mbampt.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamservice.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamscheduler.exe

Note: If using a software firewall besides the built in Windows Firewall you'll need to exclude MBAM.EXE and MBAMSERVICE.EXE from it as well

Note: Once that's done, please make sure that if either of those programs has any sort of web filter, that you add the following as a trusted site:

Check your Anti-Virus/Internet-Security application to see if you can add exclusions for specific applications/files to ignore.
You may need to contact their technical support or check their support website for instructions.
You will need to set your Anti-Virus/Internet-Security to ignore/exclude the files I listed above.

Hello Maurice.  


I have followed the instructions above in both your emails.  Had to boot in safe mode to do the uninstall of Malewarebytes via the control panel.  In normal mode, the machine froze (just stopped responding), but never produced a minidump file.   I cleaned the installation as instructed.  Reinstalled a new version of Malewarebytes as administrator.  I have set the excludes in MS Security Essentials as you instructed.  I could not figure out how to tell MS Security Essentials (or the Windows Firewall) how to specifically trust data-cdn.mbamupdates.com, though.


When I installed Malwarebytes, I immediately ran a scan (after I put in my license key).  It completed successfully in about 22 minutes.  I rebooted the machine.  This was about 10:30 a.m. PST.  I have rebooted the machine several times since then, surfed, played a game, played some videos, synced my iPhone, and run Outlook and Excel.  I did another scan about  2 pm. PST.  It completed in about 20 minutes with no threats found.


So far so good.

Hello Maurice,


I'll add that one of things I did was stop using my Sandisk Readycache SSD with Expresscache software.  It has sometimes made it difficult to diagnose/correct issues but generally if I disable (remove) the drive, I can fix problems and then reinstall it.  In the case of the above issues, I've had to disconnect it permanently.  That lengthens the boot time of my computer but at least it boots!  It did work fine with version 1.75 and below of Malewarebytes but not so with 2.xx.


Best regards,
