My Malware Bytes Won't Scan.

Recommended Posts

Hello there.


Just as of yesterday my Anti-Malware Bytes won't scan. And it also says my system is not protected. I never had this problem before, and I don't know what to do.

Usually the message that pops up when I hit scan is

"Malwarebytes Anti-Malware has stopped working. A problem caused the problem to stop working correctly. Windows will close the program and notify you if a solution is available."



So any ideas?

Hello and :welcome: :
The error message you report sounds as if MBAM is crashing.
Let's start with some routine troubleshooting:

  • Please follow the steps in this pinned topic to uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x -- it's important to reboot the computer when prompted by the removal tool and it's a good idea to reboot again AFTER reinstalling
  • If that does not correct the issue, then please read the following and attach to your next reply the 3 requested logs - Diagnostic Logs (the 3 logs are: FRST.txt, Addition.txt and CheckResults.txt)
  • NOTE: More info about v2.2.0 HERE; User Guide ONLINE; User Guide PDF; FAQ: Common Questions, Issues, and their Solutions

Please let us know how it goes.

Let me just say Thank You. And yes it did work. I used step 1 and it did the trick.

However there's one part I did not do which is this

"Now setup any file exclusions as may be required for your Anti-Virus/Internet Security/ Firewall applications. You may use the guides posted in the FAQS here or ask and we'll explain how to do it."


Now do I need to do this as well?

Thanks for letting us know you resolved your issue.
Normally, it's not necessary to set those mutual exclusions between MBAM and the AV.
If everything is working OK, then it's probably not needed.
If you wish to do so proactively, the attached screenshot shows how to add the AV folder to MBAM exclusions, and the instructions below explain how to exclude MBAM files in the AV.

Please exclude the following files from your Antivirus Software for your version of Windows:

For 32 bit versions of Windows XP, Windows Vista, Windows 7 & Windows 8 & Windows 10:

  • 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\mbamresearch.exe
  • C:\Program Files\Malwarebytes Anti-Malware\mbamscheduler.exe

For 64 bit versions of Windows Vista, Windows 7 & Windows 8 & Windows 10:

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

Note: If you are using a software firewall besides the built in Windows Firewall, you'll need to exclude MBAM.EXE, MBAMSERVICE.EXE and MBAMRESEARCH.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:
