Which URLs are used for updates?

Hi,
I’m wanting to setup my firewall to allow avast to update.
Which URLs does it use for virus and program updates etc?
thanks

The process performing the updates is called “avast.setup”. Its location (path) changes.

The url’s of the servers for updates, AFAIK, are

download*.avast.com

(note the " * " ).

I would also like to ask which firewall you are trying to set avast up with as if it is a firewall that combines hips then there are three avast services that should be set to allow all in the applications list of your firewall,
( avast service, avast setup and avast gui ).
