My GF's 9780 had the same icon... Basically if you go into "Messages" you'll see sort of an update for a game from that compagnie. Basically as soon as you delete it, it's gone. If after the deletion of that "fake upgrade" it's still there, simply reboot your BB.
It is weird. I mean , if there is an icon, it is a kind of shortcut which intentionally shall bring you to the related application. So..if nothing happens I guess the RIM has to do something to such "crap" devise. Mine is BB 9780 as well and when I see such "creepy bugs" it makes me mad.
