Is there a way is there a way in Avast block software from calling home.
Generally that is a firewall task, preventing executables calling home.
Avast Pro doesn’t have a firewall.
Even for those that do have a firewall (AIS and avast Premier), I don’t know if blocking the executable from calling home would be 100% possible (I don’t use the avast firewall either).
However, I can do it on my firewall Outpost Firewall Pro9.1 - but blocking an executable from connecting to the internet may not be completely what you want.
If the program has a legit reason to connect to the internet (and uses the same executable), you wouldn’t just be blocking it calling home, but any legit internet connection.
