For me, my understanding of the “Settings → Status Bar → Virus definitions version”. is that you are informed if the virus definitions are out of date, not that there is an update available.
Now what that duration is before it would be deemed to be out of date I have no idea. If you take the example of the WSC/WAC it is 7 days before they are considered out of date. You could test that theory by not updating for a couple of days, though that isn’t risk free if your browsing habits are exotic.
