I wonder how many AVG users have been tempted to abandon AVG for this very reason and give Zonealarms new package a try.
There's also a possibility that the AVG site itself is experiencing difficulties and cannot push the required updates out to users.
If this is the root cause of your issue, you should see a notice to this effect on the AVG website along with a timescale for a fix.
Security programs interact with your system on a fundamental level, and if you have more than one anti-virus program installed at the same time it can cause problems -- such as preventing you from updating one or both of them.
Alternatively, your firewall might be incorrectly marking AVG updates as potential security threats and preventing them from coming through.
