The first of the remake videos begins, with Happy99.
Happy99 is famous for being the first modern email worm to achieve true widespread status, as it would reply to emails and usenet posts with a blank message and the worm executable attached. Once run, the worm displays a fireworks animation to disguise its activity, replaces several Windows files to further spread itself, and begins its spreading routine.
