It seems some domain of avast is difficult to be connected in the mainland of China.
Please add a feature which makes avast be able to connect to internet bypass a socks5/http proxy, or just use the setting in “internet option” .
Thanks a lot!
Sorry, I make a mistake.
Use “by” to replace “bypass”

I think this will make things more clear.
