It might have come with audiogalaxy or kazaalite, but I'd have thought it would have popped up before now. I'm thinking it must have come with the Shockwave download I did earlier. Which is extra disturbing, since I was at lego.com when I authorized it (wanted to play Junkbot.) Stupidly, I did not check file dates before deleting everything gator-related.
Anyone else find themselves infected after authorizing a Shockwave update?
