Yes, I've a number of users all with problems. All using the free version 8. The main problem appears to show itself as an Update Manager error: The connection failed.
In every case I've looked at so far, this is not a question of the user's computer or Internet connection being at fault. This is what is reported regarding regarding the AVG FREE Update Server:-
Our technology department is currently working on improving one of the main servers responsible for providing updates of AVG Free Edition. This maintenance may have, under specific circumstances, effect on availability of update files on our servers. Backup systems, which are now in charge of providing updates, may be from time to time overloaded with customer requests and we are doing our best in order to improve their function to remedy this issue. If you encounter issue with “Update failed”, please retry in a few minutes to update AVG manually (open AVG User Interface, click the “Update now” button).
We are sorry for any inconvenience this may cause. In a week time, new improved update servers should be available.
It is now well over a week, so one might have expected a better service by now. I get the impression that there are a lot of unhappy people out there still trying to use this version of the software. Whilst I am not convinced the problems are caused by the "new" version 8 software, it seems that AVG is doing themselves no favours with the continuing problems users are experiencing.
It must be said that there's no such thing as a free lunch, but if folk trial the free version with a view to subsequently going for the paid application, they'll not be impressed with this inability to regularly update.
