There is indeed something fishy going on... Those descriptions sounded very familiar to me, and after a quick search I found out that the descriptions and all come from software like GIANT Anti-Spyware and from other non-microsoft webpages (which of course some people have big influences on those kind of pages)...
So, now even MS is using those not-entirly-correct (some even wrong) definitions just because those people shout the loudest on their forums or do they simply blindly take over the company without correcting things (MS bought Giant Company Software recently)?
EDIT: hehehe, while I was writing this, Segosa already gave it away
