Windows Crashes Related to mwac.sys


Recommended Posts

Lately, I've been experiencing random crashes and my computer rebooting unexpectedly.  I posted my memory dump files on the Microsoft forums (thread located here).  Someone analyzed the dump files and said that mwac.sys is causing the crashes.  He recommended I uninstall MalewareBytes, but I wanted to see if there was another solution.  If I do end up needing to uninstall it, can I get a partial refund for the license on this PC?

Hi,

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

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
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

Spoiler
  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • 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.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

Yes, if the beta does not resolve the crash then disabling Web Protection until a fix is released will be the only workaround (while still keeping Malwarebytes active on the system of course).

Additionally, I'd highly recommend installing the Malwarebytes Browser Guard browser extension if you haven't already.  It's available for Chrome (and other Chromium based browsers like SRWare Iron which is my own browser of choice, as well as Microsoft Edge Chromium among others) as well as Mozilla Firefox.  You can get it by clicking the link to the version for your browser in my signature below.  It has much of the same capabilities as Web Protection in Malwarebytes Premium except it only protects your browser, not the entire system, though the web browser is by far the most vulnerable target on most systems so it is the most crucial to provide protection for.  Additionally, Malwarebytes Browser Guard includes behavior based blocking which is only possible from within the web browser using a browser extension.  This allows it to block sites based on known malicious behaviors, layouts, structures, copy, code and more, even if the site is unknown to the Malwarebytes web block databases.  Sites blocked this way include tech support scams among others.  The extension also includes blocking for many common ad servers and trackers to guard your privacy when surfing, and it also blocks clickbait links/sites.

Once the issue is fixed and you are able to activate Web Protection once more you may keep Malwarebytes Browser Guard to augment your system's overall protection as it works quite happily alongside Malwarebytes Premium, including the Web Protection component.
