This virus has seem to have been going around in every long hair yahoo group that at least I am a part of. I first seen it come up in my yahoo group and they had used my name to send it out. It has also come in my E-mail a few time under different sender names. Here is a link to find out more about this virus and how to clean it up

I would just not download anything that has to do with porn or a porn picture because that is how it seems to be getting out or at least make sure the the sender, if it is a name of someone you know, really did send it.
