It's the Santy Worm which has just been released and is gaily zapping fora all over the place. Once it's got into your site it goes round and changes all program pages including HTML so that it says

NeverEverNoSanity WebWorm generation nn. where nn is a number. In my case 17.
I've had to reload the entire site and I've taken the board offline until I can figure out the security issue.

Turned out that my host hadn't updated PHP. All done now. [:D]
