MB 4.01.31 1.0.12741

Just updated Windows 10 to 18970.1005 x32

Did not uninstall MB prior to upgrade

Following successful Windows upgrade, MB scanned OK

Then I turned off web protection from tray icon options 

Clicked on "Manage protection settings" in warning notification"

MB disappears.

Restarted, all OK, cannot reproduce error.

Any logs needed?

Hi @John A,

Thanks for the report.

When you say Malwarebytes disappeared, what are you referring to (user interface, tray app, etc)?
When this occurred, do you know if the Malwarebytes Service (MBAMService) was still running or not?
Does a folder named "CrashDumps" exist in %localappdata%? If it does, please check if there are any recently created .dmp files inside.


Attached.  If it happens again I will run the tool before restarting Windows

Thank you. Running log gathering with MBST immediately after it occurring again will definitely be helpful!

Please do the following now as this will provide us with additional information if the issue does occur again:

  • Open Malwarebytes.
  • Click Settings.
  • Enable the, "Enhanced Event Log Data" setting.

Sorry, I was a bit slack with details on this one.

The MB icon disappeared from the tray.  I didn't check services however around that time the event below was logged. There are two folders called "crashreports" in  %localappdata%, both empty.

The original failure must have been associated with Windows feature update.  I have done two further feature  updates to Windows 10,  both with MB4 Beta running - no issues occurred. Normally I would disable any third party security apps when doing a Windows 10 feature update.

MB4Beta  is running beautifully.  It is much better than the early versions of MB3.
