If we dumb it down to "There's an ickky virus going around which sill hurt your PC!" then it's no use to us geeks with a clue. Just leave the real explination and put "Install this to fix the problem" at the bottom of the page for the idiots.

Not at the bottom of the page but at the top. Most users wont read lots of meaningless (to them) text. Where as a technical person will becuase they know there might be somthing important there.
