I've a problem : Windows 10 crash once shutting down with blue screen, this appears since one month on my PC.

I've latest signature & latest avast soffware (Avast Internet Security) and everything is activated, Windows 10 has normal behaviour (and checked latest updates) this is just when i want to shutdown my PC that i've blue screen while shutting down.
I searched a while ...

and just found that if i disable temporary all agents Avast before power down i still have problem.
BUT
if i remove AVAST using Windows uninstall, my PC stop to crash while shutting down. If i reinstall latest Avast the problem appear.
So in think the problem has link with Avast. Please help !
