Received the following directive from the Malwaresupport via mail: "I would ask you to update the forum with the information that crashes are not appearing after adding a longer delay between the scan completing and the "Quit Malwarebytes" option being used. In such a way, our engineers will be notified and be back to you as soon as possible." I reported the same already in post #14...

Some more input from Testing: I did try to applicationwise disable Services and related Startup items. The result was that after disabling the following Services: AcronisActiveProtectionService Acronis Managed Machine Service Mini Acronis Mobile Backup Server Acronis Mobile Backup Status Server Acronis Nonstop Backup Service Acronis Scheduler2 Service Acronis Sync Agent Service and subsequently disabling the following Autostart entries: Acronis Scheduler Service Helper Acronis TIB Mounter Monitor Acronis TIB Mounter Monitor The likelyhood for crashes reduced significently. Not none but very little. - So it seems to me to be a really weird combination of various things... To double check I ran the same on my notebook - but wasn't able to reproduce there - until I activated my Malwarebytes license. Once I did, the same crash happened there as well... Maybe this helps a bit as well...

Further Input: Noticed that Windows-Desktopgadgets were a rather old version - so updated the same. No improvement though from this. I also tried to cross check - sadly not very successful: 1.) Disabled OneDrive and the Windows-Desktopgadgets - still experienced a crash 2.) Disabled all entries from the startup tab @ task manager - still experienced a crash Sorry fo not having better news...

Quick Question - what is telemetry.malwarebytes.com? Could the unavailibility of this cause such issues?

Phewww.... quite some heavy testing for hours... OK, so I did follow those instructions for a clean boot and wasn't able to clearly reproduce those crashes. I tried to slowly reenable the Applications listed in the startup (task manager) and it seemd like the crashes would happen again if OneDrive and the Windows-Desktopgadgets were running (no services having been reenabled though). Saying seemd as I also had a case where it looks like neither of both was running - but this situation wasn't perfectly clear and I can't be more precise in this regards. Having only one of both running I wasn't able to reproduce the crash either... Please find attached again 2 dmp files - one named "None_running_mbamtray.exe.7932.dmp" - which represents the questionable case described above. mbamtray.exe.8484.dmp None_running_mbamtray.exe.7932.dmp

I am using Malwarebytes only on demand - so the service is being launched as well - it's set to start type=manual I quit Malwarebytes via the tray app after the scan has been completed and I closed the respective Window - so I certainly see the result before quitting... I tried now 4 times and it did not happen in safe mode so far. I have to point out though, that in safe mode I also don't get a UAC popup asking for permit for Malwarebytes to make changes to the system. With 5+ minutes I didn't have a crash - but with something between 3 and 5 minutes I still had repeatedly. Not sure if there is a big difference between 3 or 5 minutes though.. or not having a crash with 5+ minutes was just good luck. Please let me underline though that I couldn't and can't put too much time into double checking with this approach repeatedly - so not sure to which extent these results are very reliable. Thanks for your help!

No worries - I just opened it a little time before as I had the impression this wouldn't be read by others than (still very mature - so no offense please) users. The Ticket Number is 2944764...

Sent via mail as well now.. But here we go... mbst-grab-results.zip mbamtray.exe.12056.dmp

Thanks a lot! Do I have to look for the new topic elsewhere? If so could you please give me an hint where to find it - I sadly didnt succeed... I tried the Malwarebytes Support tool already - didnt really change anything. Having uplaoded the logs and the files already - should I again pass it on to you by attaching it to the support ticket confirmation mail? BTW - just tested with the latest version - the problem still persists... Thanks a lot! mbamtray.exe.12056.dmp

Is this actually read by the Malwarebytes staff?

Thanks for this guidance, highly appreciated! Based on this I activated my license and disabled the option for Malwarebytes to register in the Windows Security Center. Subsequently I removed the scheduled scan. The automatic start with Windows was disabled already. The rest I left alone in order to not changing the situation too much for the crash analysis... .. and this is exactly what I did - and what often leads to the crash described above. I checked if running Malwarebytes as Premium changed anything in this regard - but was able to trigger the crash again. I'm attaching the related dump again... BTW - I ran Dism /Online /Cleanup-Image /ScanHealth and sfc /scannow just to ensure being safe on this side - no issues have been reported... mbamtray.exe.13712.dmp

Seems the same happens to me as well - and I could notice this on more than one machine. So far I usually managed to observe this behavior after starting Malwarebytes, initiating a scan right away and closing Malwarebytes again afterwards via the system tray icon. Still this doesnt show up always - and I haven't found when or when not. Having tried to repair via the Malwarebytes Support tool (at the other machine) this didn't help for long at least. Please find attached the logs gathered through the Malwarebytes Support tool as well as a generated Dump. Here what the Windows Application log tells: - System - Provider [ Name] Application Error - EventID 1000 [ Qualifiers] 0 Level 2 Task 100 Keywords 0x80000000000000 - TimeCreated [ SystemTime] 2020-03-08T09:38:53.378470600Z EventRecordID 16595 Channel Application Computer WSCDBAK Security - EventData mbamtray.exe 4.0.0.577 5e505ac1 Qt5Core.dll 5.14.1.0 5e4172be c0000005 0000000000219d05 1594 01d5f52d5eb1d482 C:\Program Files\Malwarebytes\Anti-Malware\mbamtray.exe C:\Program Files\Malwarebytes\Anti-Malware\Qt5Core.dll 05908203-b2ad-499e-91be-6cf1269d924f Thanks a lot for your help! Chris NB: I havent the license activated as I do want to run Malwarebytes as a second line protection to Windows Defender and havent yet found how to achieve this running Malwarybytes as Premium...(just mentioning in case this matters) mbamtray.exe.10812.dmp mbst-grab-results.zip
