Hello David,
We appreciate your patience. We suspect your update reference is the release date & time of the virus the definitions (which is not necessarily the time it was installed on the computer. It could be better if you share the screenshot of it to check & confirm this.
I just noticed that when opening the AVG interface it states that the virus definitions were recently updated and in fact it stated 3hours ago. The problem is that the computer was switched off at that time so how can it have updated the virus definitions. This sort of thing affects the credibility of the protection software.
