I am just an user but I guess the problem is Zonealarm.
Avast acts like a proxy, sitting between your other software and the Internet.
Probably Zonealarm is blocking Avast so you cannot connect through it.
Try opening Zonealarm rules list, delete any rule related to Avast.
When you try to connect, Zonealarm should ask you to create new rules, authorize.
If that doesn’t work, there is a chance that Zonealarm coflicts with Avast.
