Also it shows me internal server error when signing in to avast account via GUI. Signing in to avast account via website shows no problem, but it still shows me that Home network security is not installed and give a red colour and also on my name MyName - HP it says unknown. I reported this issue few times and still not fixed. By the way, about the internal server error i already gave the feedback via gui. Hope Avast team reads it.
Edit: Signing in to Avast GUI works now, but there's a problem that i reported few times and still not solved. You can review it by one of my support ticket. Ticket number is #BYU-790-31187
