Hello @hydr0

Your dump is consistent with what we have a fix for coming out soon.

Please try restarting your system if you haven't done so already.  It is possible that the older version of the driver is still loaded into memory resulting in the issue repeating.  If that doesn't resolve it then please try a clean installation, making sure to install the beta afterwards to test:

  1. Run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here
  4. Once that's done, enable beta updates in Malwarebytes and check for updates, ensuring that it downloads and installs the new beta, then restart your system and test/verify that the issue is resolved

Please let us know how it goes.

Thanks

So the beta updates is on and you still do not have the new beta version? Please do a manual check for updates.

Beta updates is turned ON and it says I'm up to date.

This is not right. Should say 4.0.4. Where did you download this version?

One thing I did do was get rid of the browser extension for chrome as it was causing severe lag and unresponsiveness for most of the sites I visited. have not had a bsod since the last one while being on the latest component version

Thank you

Please try uninstalling and reinstalling Malwarebytes for Windows using the Malwarebytes Support tool.  And then activate beta updates again.

Uninstall and reinstall using the Malwarebytes Support Tool
https://support.malwarebytes.com/docs/DOC-2674

Please have lots of patience with the tool.  The first phase is a cleanup and does require a Windows Restart.
After the Restart, it may take 2 - 3 - 4 minutes till the Support tool screen shows up.   Please be patient and have faith.  Wait for it, whatever it takes.
The 2nd phase is where it offers to do a new Install.

 Let me know if that clears up the issue or not.
