An update to the antivirus engine pushed early this week (around 6-7 days ago) has almost surely been causing BSOD issues.

It happens with both AVG and Avast users, it causes crashes with well-known good .sys drivers such as RivaTuner’s RTCore64.sys and CPU-Z and GPU-Z low-level drivers.
I have had to uninstall the antivirus because my PC would crash every 10 minutes randomly.
