The Register has a story
here although no technical details.
It wouldn't surprise me at all - my day job is selling IT security software, and the number of times I see that customers haven't got up to date patches and all the rest it's no surprise that this sort of thing happens.
BTW, for a laugh, check the "Odds and Sods" for some fun stories - the "pooing doll", the "natural harvest" recipe book, the "humping dog" USB stick . . . actually, maybe THAT'S where the virus came from !
