ok, now I get it...norton just always looks for an update...which you should dissble, as it'll take your bandwidth...avg, ya, you can pcik scheduled times, but I wouldn't do that either...taking your bandwidth when you might need it, just update manually...best choice
Sorry I didn't make my posting clear. I had Norton scheduled for a time of day, but even if I wasn't on line at that time, it still checked and downloaded updates when I next logged on. With AVG if I am not logged on at the sceduled time, then the update is missed, and it doesn't automatically update when I do log on. The manual updates work fine, so as you say I'll just do a manual check every few days. Sorry for the confusion.
set the time in the avg control centre and it should dial and update whenever you want it too but personally i prefer to do it manually, although grisoft say a release is put out monthly, i find that i can get new updates every couple of days
