BSOD Unknown Reason

The dump file on the 18th was caused by Quick Heal again. The later ones appear to be due to bit flips. I would recommend enabling Driver Verifier on all third-party drivers using the following instructions:

1) Search for verifier using the Start Menu and select the verifier.exe, accept the UAC prompt and you should be presented with the following screen:





2) Tick the following options as shown below





3) Ensure that you select the option to enable you to select drivers yourself





4) Select all drivers which are not Microsoft related and then click the Finish button. Afterwards, please reboot the computer and Driver Verifier will continue to run in the background. Please do not select the drivers which are prefixed with dump_

Please run driver verifier using the following settings for 48 hours.

Warning: driver verifier could cause boot issues and/or performance issues.

• Make sure that you have recovery media, if needed you can create it.
• Configure a restore point prior enabling driver verifier.

Resetting driver verifier options (recommended in this order)

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.
