MBAM 3.5.1 auto start fail

Recommended Posts

Had been so reliable I took it for granted, would always get the scan pop-up, but failed to get one today did some checking and was not running.

Can start manually, but won't resolve to Win7 notification area - previously when I closed the mbam window the program would still run and show in the notification area - now it exits the program.

The Settings/Protection "start malwarebytes at Windows startup" button is on but has stopped working. Mbam is set to display icon and notification in control panel.

Support tool log attached:

According to your logs it appears as though it is failing to start because it isn't seeing any user logged in when trying to start the tray:

07/09/18    " 05:42:29.153"    34959    0950    0fa0    INFO    ServiceControllerImpl    ServiceControllerImplementation::StartApp    "ServiceControllerImplementation.cpp"    87    "Starting 'C:\Program Files\Malwarebytes\Anti-Malware\mbamtray.exe' in session 0x1"
07/09/18    " 05:42:29.153"    34959    0950    0fa0    ERROR    ServiceControllerImpl    ServiceControllerImplementation::StartApp    "ServiceControllerImplementation.cpp"    191    "System error 2 calling CreateProcessAsUser"
07/09/18    " 05:42:29.153"    34959    0950    0fa0    INFO    ServiceControllerImpl    ServiceControllerImplementation::StartAppIfNotRunning::<lambda_f19f16e888e1a75a06bb8a50e77ae0af>::operator ()    "ServiceControllerImplementation.cpp"    1853    "Did not start C:\Program Files\Malwarebytes\Anti-Malware\mbamtray.exe - it is possible that no user is logged in."

The tray runs in user mode, so if no user is logged in it will fail to start.  There could be a few possible reasons for this, but we'll start with the simplest and work our way from there.

First, is timing.  It's possible that it's taking too long after system start for the full user login process to complete to the point where Malwarebytes is able to load the tray in user mode, so let's try putting a delay on it and see if that helps:

To begin, let's try configuring protection to start after a delay:

  • Open Malwarebytes and navigate to Settings>Protection
  • Scroll down the tab until you locate Startup Options
  • Toggle the setting Delay Real-Time Protection when Malwarebytes starts to On
  • Click the drop-down menu next to Delay protection for: and select 120 seconds to start
  • Restart your system and see if it is now able to start properly after waiting for a few minutes
  • If that worked, you may try backing off the delay by reducing the number of seconds in the drop-down until you find the shortest delay that works and if it doesn't work, you may try increasing the value until you find one that does work (assuming any of them do work)

If that failed, you may toggle the Delay Real-Time Protection when Malwarebytes starts setting to Off once more then proceed with the following to determine if the service is the issue:

  • Click on START and type services.msc and press Enter
  • Scroll down the list until you locate Malwarebytes Service in the list and double-click on it
  • In the properties dialog that opens, click the drop-down menu next to Startup type: and select Automatic (Delayed Start) then click Apply and OK then close the Services window
  • Restart your system then see if Malwarebytes starts up on its own this time.  Give it a minute or two though, as it's going to be delayed rather than starting immediately

Please let me know how it goes.

No go. Delay Real-Time Protection increased to max of 180 secs - still fails to start.

services.msc entry for Malwarebytes set to Delayed Start but mbam fails to start after hard and soft reset.

setting in  services and protection delay in mbam returned to original settings.

The only change in my setup is that I disabled and transferred a Malwarebytes license on my local network from a PC taken out-of-service and placed successfully on a new machine.  Seems unlikely it would affect this PC though.

OK, thanks.  Did you try disabling self-protection as suggested above by lbdonato?  If not, then go ahead and give that a try.  There's a recent bug that's cropped up where self-protection causes Malwarebytes to fail to launch on startup on some systems which is being investigated by the Developers.

By the way, if disabling self-protection works, if you could also please do the following as it would help Malwarebytes' Developers to track down the cause of this issue so that they can more quickly get it fixed in an upcoming release we would be most grateful:

  1. Download and extract CaptureTrace-Logman.zip
  2. Re-enable Self-Protection
  3. Navigate to Settings -> Protection
  4. Scroll down to Startup Options
  5. Disable Start Malwarebytes at Windows startup
  6. Reboot the computer
  7. Once rebooted, find the files from step 1
  8. Right click on Capture.bat and choose Run as Administrator
  9. Once the black window comes up, it will tell you to reproduce the issue
  10. Double click the Malwarebytes desktop icon and wait 30 seconds
  11. After waiting, click on the black window from step 9 and press Enter
  12. Zip up all the files in the folder that opens and attach them in your reply

Auto-start problem has resolved itself.  Usual suspect is last MS update. 

Just for the record this problem was isolated to a unique hardware combo:

Affected: i7 920/IntelX58

Not affected: Core2/P45, Core2/975X, i7 8700/Z370

all running Win7Pro except the i7 8700 on Win10Pro
