IPs for AV Update through outgoing firewall

Avast Free Antivirus / Premium Security
1

I am tightening up the pfSense firewall at my company to restrict more outgoing communication. I have blocked outgoing to some countries, which I believe is also blocking Avast from running scheduled program and antivirus updates. Is there a list of IP addressess (or FQDN) used by Avast for program and AV updates that I could get to add an exception in my firewall? Thanks.

As far as I know there is no such list as avast has servers in multiple countries and the locations can change.
Why not simply allow all communication from the avast software ?

The servers for updates can be found in the servers.def file.
But there are many and as Eddy mentioned they change… :wink:
