Windows 10: Programs crashing, random BSODs, lots of instability

My brother's computer keeps getting BSODs, and he's having other issues where programs are randomly crashing as well. It can happen to any program, and Windows services are randomly crashing too according to Event Viewer. I've done the usual stuff: updated all drivers, ran Windows updates, ran sfc /scannow and the DISM equivalent, but nothing is fixing it. Logs are attached. He was having the problem on 1903, I updated him to 1909, still happening.

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.

Sorry, Bitdefender is a problem: BSOD BAD_POOL_HEADER - mwac.sys - Malwarebytes Anti-Malware Help - Malwarebytes Forums

 

Random BSODs "Bad_Pool_Caller"


This BSOD happens anywhere, irrespective of BitDefender. It takes place even when the antivirus is MSE in case of Windows 7. The most common cause is an expired trial or a cracked installation. Some examples:

• Norton: Windows 7 Random bsod caused by tcpip.sys - Windows 7 Help Forums
• MBAM only: Epic BSOD error appears just after few seconds from boot Solved - Windows 7 Help Forums
• McAfee: BSOD on Internet Related Programs (tcpip.sys) - Windows 7 Help Forums
• Avast: Bad Pool Header 0x00000019 at random times - Windows 7 Help Forums
• Avira: BSOD randomly Crashes my Laptop and freezes at Memory dump 100 - Windows 7 Help Forums
• Crack: BSOD every 6 minutes, also recent freezes - Windows 7 Help Forums

We are on our way of troubleshooting. If the uninstallation and reinstallation does not work, we will take the next step.

I, in general, know what I am doing and what I am suggesting. If I feel that I am unable to control the issue, I will definitely ask for help.
