How do you install the new version when you are behind a firewall. I can download the executive file but when starting I guess it is trying to connect bact to the Avast server and the firewall does not allow that. I can’t do automatic definition updates as well.
Time to get a gun and make the owner allow avast ;D
At least in theory you should be able to install avast using the full package.
You can download the latests vps on a system that allows you from : https://www.avast.com/download-update
Transfer it to the system you want them and run the vps installer.
