I don't normally pass on these, but it comes from the ISP I use, ntl, who are not hoaxers (not much good as an ISP either, but that's beside the point - and they are free):

Virus Alert ntl have become aware that many customers have recently become infected with the W95.Hybris.gen worm. This worm spreads via an email attachment while the text of the infected email may contain the text "Snow White and the Seven Dwarves".

If you are sent such an email please delete it immediately.
