Have you tried.AVG.Tools.Advanced Settings. Ignore Faulty conditions.And make sure nothing is ticked.Or.Components.Double click update Manager.And make sure Start automatic updates is ticked.Also it should tell you when it was last updated.
any idea how i find out what? or do u think it best i take it somewhere for them to have a look? just dnt understand it because up until this morning the only problem i was having with avg was that it wouldnt update but it still said antivirus was up to date and switched on. i could also get on the internet when it was on there. but then as soon as i uninstalled it earlier and went to install it again, its saying all this and blocks me gettin on net. but it also tells me on overveiw that last update was today :S but the update bar gets so far then freezes and says update manager failed!
