Back in 91 or 92 there was an exe on a floppy of VGA porn a kid had downloaded off of a BBS and passed around school and when you ran it something that looked a lot like this happened, but it didn't actually cause any problems so eithe rit failed or it was just a really crappy demo attempt and not a virus at all.
It made a siren noise, flashed WARNING! THIS SYSTEM IS GOING DOWN! in big red letters and then zoomed in on a grainy, EGA vagina and locked up the computer.
