hi,
its the first time i'm writing here, because i haven't found a solution for my problem. i use sygate personal firewall 5.5.
to update avast by rigth-click-menu on tray-icon i must copy the file AVAST.SETUP (this file will be generated during the update process and this must be able to connect the internet and after updating, it will be deleated) and allow it to connect the internet and then deleting it. therefore avast is creating this file and sygate thinks, that this file was always be there.
i think there must be a similar solution for the problem, that avast can't check for updates. if the firewall "allow all" avast is checking for updates and giving me a message. if the firewall ist in normal-mode, avast isn't checking for updates.
somebody knows which process i should be allow the connection (i have all *.exe files in the avast folder allowed the access to the internet)
