BSOD Caused By MWB Privacy

My Windows 10 20H2 system will crash periodically with IRQL Not Less or Equal BSOD. The Crash Dump Analysis from my WhoCrashed app points to the MWB VPN Tunnel Driver (mbtun.sys). It takes several attempts to get my system to boot properly after the BSOD crash.

I have read the other posts on this problem and want to know if you recommend installing the beta 2.0 version? I ran the MWB Support Tool and logs are attached.

Greetings,

Yes, please try the following to see if it corrects the issue:

Uninstall Malwarebytes Privacy
Uninstall Malwarebytes Privacy VPN Tunnel Driver
Restart the system and install the beta from here: https://downloads.malwarebytes.com/file/mbprivacy-offline-beta-2.0

Please let us know if that fixes the issue or not.

Thanks

Was having the same issue as the other fellow in the thread. When I used support tool it didn't remove the Tunnel Driver for whatever reason. When I manually deleted it, the reinstall worked.

Many thanks, @exile360!

I have found that it is best to use the Control Panel instead of using MBST and Uninstall Malware Privacy first then uninstall Malwarebytes Privacy VPN Tunnel Driver second. Also if the Malwarebytes Privacy VPN Tunnel Driver doesn't uninstall the first time then try a second time from the control panel. Then if that fails you can go to the Device Manager and uninstall the Tunnel Driver from there in Network Drivers. Also if you happen to see mbtun 2, mbtun 3 and mbtun 4 in Network Drivers then also uninstall those too from the Network Driver list. Then you will not see the BSOD when installing the last beta posted above.

Hope that helps anyone that is having issues with BSOD.

Thanks exile360 and Hardhead. I did find mbtun 2, 3, and 4 in my network drivers, so I uninstalled as recommended. I will install Privacy beta soon and let you know if it fixes my BSOD issues.

Here is something interesting I encountered after installing 2.4.

I was having problems submitting a reply here. Here is the popup error I was getting after clicking on the Submit Reply button:

I had MWB Privacy turned on when I was trying to reply. When I turned off Privacy, I was able to reply.

I typed "I will try again." and clicked on the Submit Reply button. Privacy was turned on. The popup error appeared.

I turned Privacy off and was able to post this reply.

Try rebooting and log back into the forum with Privacy turned on and see if that clears the issue. Post again please.

Rebooted and logged back in to forum with Privacy turned on. Will now click on Submit Reply. Received same popup error as posted above.

I am using the latest release of Chrome, and I have MWB Browser Guard paused. Same popup error result. When I turn Privacy off, I am able to submit a reply.

Seems like the forum spam filter is getting in the way of your posts. I think @AdvancedSetup can adjust that for you.
