Malwarebytes keeps removing important login file

Recommended Posts

For the past couple of weeks Malwarebytes is deleting the following file: HKLM\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\WINLOGON|USERINIT 

when it does this it kicks out the user who is signed in and when they try to sign back in they are greeted with a black screen and are unable to open anything. 

Any idea why this is happening? i run malwatebytes scans on these machine's when this happens and it tells me "no threats found".  I created a support ticked with Malwarebytes on Friday but have yet to hear back from them.

The affected machines have Malwarebytes Endpoint agent installed along with Mcafee Endpoint security threat preventation.

Thank you

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance

    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.

"Might" be part of the issue.

That is a registry key, however deleting it shouldn't cause any visible change during the current Windows session for the currently logged on user, at least that is my understanding.

That said, I would advise excluding the item from detection by Malwarebytes for now just to be safe.  To do so, perform a Threat scan (the default scan type) with Malwarebytes and allow it to complete.  Once it does you should see the registry detection listed.  Uncheck the checkbox next to it then click Next and select the option to always ignore the item so that it is added to your Allow list/exclusions in Malwarebytes and will no longer be detected by future scans.

If this is a false positive, a member of the staff should be able to aid you in addressing the issue by correcting the detection in the Malwarebytes database.

That is odd, Ransomware Protection shouldn't detect any registry keys.  It is only supposed to target processes.  In fact, as far as registry keys are concerned, they aren't even supposed to be checked in real-time at all and should only be analyzed during scans.  That is why I suggested performing a scan to create the exclusion.
