Not that Avast scan my traffic, but it seems that connects
with other ips. Avast would not have to go out on the Internet.
And that seems to tell me my firewall.
Some IPs which connected seems also AVAST.
There are other connections related to avast than just updates, participating in the avast community, community features, news service and even if you disabled all of this you still get the discount offer in the GUI that is updated everytime you open it.
