Avast gives BSOD "driver_irql_not_less_or_equal" when selecting "Disable shields

Hello,

When starting a pc game I always kill unnecessary processes for best performance (iCloud, OneDrive, Apple and HP stuff etc) and I disable Avast shields until computer is restarted. Normally this does not cause any problems except that I have had a BSOD a few times with following error code: driver_irql_not_less_or_equal

Any ideas?

Thanks in advance
