I am having this problem for 2 weeks now. When I try to update the virus database automaticaly
it gives me errors (cannot connect), and when I try to download the files manually it won't do it.
I am thinking about abandonning AVG....
I just tried to update AVG Antispyware and it gave an error that the server wasn't ready to update and to try again later. Then I tried to update AVG Anti-Malware on my computer and it updated fine with no problems. Seems to be a problem with one of the update servers. They possibly are in the process of adding a new update to the server, updating the server itself or performing some other kind of maintenance. I would give it a couple hours and try again and see if you are then able to get updates.
