Could it be that the uni's firewall prevents Avast in my system from getting to the servers and locating the updates?
The update locations are in the file servers.def in the Alwil folder on your system, so that is not it. But the servers Alwil is using have had some problems the last week, so it might be that. Right click on the blue ball next to your clock and choose iAVS update.
