Problem after Windows 10 "April" 1803 Update

After updating windows 10 to Version 1803 (April Update) no Computers will be shown in File Explorer “Network” when avast is running.
If i disable avast (It´s enough to disable the avast Firewall) the Computers will be shown again.

I have avast removed with the removal tool and have installed avast again, but the Problem persists.
It seems that there is an Problem with the new Windows 10 Version?

Since installing Win 10 v1803 I am unable to launch Avast Safezone. I uninstalled it but when I go into Components to reinstall, it says to restart the computer which I’ve done several times. I am unable to scroll down the list of components.

I suggest you try a Clean Install of Avast:
