This is totally wrong, it really is about time Avast stopped playing silly games like this and concentrated on providing what we paid for, a stable ,reliable security system.
5.1 is/was anything but stable and there have been far too many version releases in a short time. Despite reinstalls and repairs 5.1 regularly fails to load shields at system start or shields/firewall suddenly just stop/turn off. I have seen this on several systems and 3 of my own. I am seriously considering removing Avast (3 year,3 machine license) and finding something else to replace it as we keep seeing extra features and "bits" tacked on but an AV that is failing to secure machines.
