Mbam 3 won't start


Recommended Posts

I upgraded my Mbam 2.x to 3. It worked perfectly, did a scan and all seemed well. To be sure all was right, I rebooted. And Mbam now won't run. I do see mbam.exe *32 in task manager, but nothing is running and nothing in tray. I'm also running Norton Internet Security and Windows 7 Pro. Any tips on fixing this will be appreciated.  Thank you.

On some computers the upgrade from v2 to v3 does not go too smoothly.   A clean re-install would probably work best on your computer if you want to give it another go at it...

Let's try this first.... (I would go with the CU4 BETA version)  (Please remember to de-activate your Malwarebytes first before un-installing or using the clean removal tool)

  1. Please follow the steps in this pinned topic to uninstall your current version of MBAM and reinstall the latest build - Malwarebytes mb-clean tool (after uninstalling you can download the latest version to re-install from HERE) (If you prefer to test the latest Malwarebytes 3.0.6 CU4 -- BETA Preview which corrects many issues with the current version you can get it from HERE)
  2. If that does not correct the issue, then please read the following and attach to your next reply the 4 requested logs - Diagnostic Logs (the 4 logs are: mbam logs zipped, FRST.txt, Addition.txt and mb-checkResult.txt)
  3. NOTE: More info about Malwarebytes 3.0.6 CU4 HERE; MB 3 User Guide ONLINE; MB 3 User Guide PDF; MB 3 FAQ: Malwarebytes 3.0 - Frequently Asked Questions


Please let us know how it goes.


Thank You,

Thank you for your response, Firefox. Actually, I had seen another of your posts and that guided me through my testing. As you recommended, I tried CU4 and used the clean tool link you provided to remove the other version. As I had mentioned, Mbam 3 works fine when installed; it's the fact that it starts in reboot (shown in task manager) but doesn't run that was my difficulty. I reinstalled 2.2 and the ransomware beta and I'm okay for now. My guess is that something between Norton and Mbam is causing the difficulty and that's too much for me to spend time on right now. But I appreciate your advice. It's possible that I no longer need Norton, but I'm hesitant to commit to that. Anyway, thanks for taking time to share this info. I will use on my next attempt, possibly after another mbam update or two. Thanks, 

david

I would keep both Norton and Malwarebytes, as Malwarebytes is not an antivirus program.  If you think that Norton and MBAM are not getting along, you can exclude the files below in your Norton. The list below is for Malwarebytes v3.  The list for v2 is different.

I would like you to add these files to your Anti-Virus exclusions list
 

  • C:\Program Files\Malwarebytes\Anti-Malware\assistant.exe
  • C:\Program Files\Malwarebytes\Anti-Malware\mbam.exe
  • C:\Program Files\Malwarebytes\Anti-Malware\MbamPt.exe
  • C:\Program Files\Malwarebytes\Anti-Malware\MBAMService.exe
  • C:\Program Files\Malwarebytes\Anti-Malware\mbamtray.exe
  • C:\Program Files\Malwarebytes\Anti-Malware\MBAMWsc.exe
  • 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

I appreciate your candor. Ver 3 is advertised as a full anti-virus, but I have doubts. Thank you. And thanks for the Norton exclusion list. I do plan to attempt the upgrade again, but only when I have several hours to focus on it. What was frustrating was that V3 ran fine; it just wouldn't start again. Your list will prove a big help. Thanks much for that.

On my next PC I'll start with Mbam without AV. I like the concept s signatures often are false positives.

I wouldn't At least leave Windows Defender on.  That is how I set them up.

Because of this.

Malwarebytes' Anti-Malware ( MBAM ) does not target scripted malware files.  That means MBAM will not target; JS, JSE,  PY, .HTML, VBS, VBE, WSF, .CLASS, SWF, SQL, BAT, CMD, PDF, PHP, etc.
It also does not target documents such as; PDF, DOC, DOCx, XLS, XLSx, PPT, PPS, ODF, RTF, etc.
It also does not target media files;  MP3, WMV, JPG, GIF, etc.

Until MBAM, v1.75, MBAM could not access files in archives but with v1.75 came that ability so it can unarchive a Java Jar (which is a PKZip file) but it won't target the .CLASS files within. Same goes with CHM files (which is a PKZip file) but it doesn't target the HTML files within. MBAM v1.75 and later specifically will deal with; ZIP, RAR, 7z, CAB and MSI for archives. And self-Extracting; ZIP, 7z, RAR and NSIS executables (aka; SFX files).

MBAM specifically targets binaries that start with the first two characters being; MZ
They can be; EXE, CPL, SYS, DLL, SCR and OCX. Any of these files types can be renamed to be anything such as;  TXT, JPG, CMD and BAT and they will still be targeted just as long as the binary starts with 'MZ'.
