Does it request to do a scan? My vista laptop just had the icon you
described, when I did a system scan it went away.
I installed SP1 and the Icon problem remained. But then I was able
to manually install windows updates (wasn't before sp1 for some reason)
I found one for defender sigs and after installing it, defender behaves
normally.
Not sure why clicking update from the defender icon doesn't work but it's
probably something to do with my IT guy handling windows update and
my box being the first with Vista on it. It looks like automatic updates
are not working and that was the cause.
