Yes, and here's the information about it on the
Snopes website . Interestingly, this particular hoax dates back to 2002.
A bit of advice for the future: any time you get a 'virus' warning, look to see if there's any date in the warning, any link to a
particular page of a website rather than just a generic 'it's been checked out by' Microsoft or IBM or Snopes or whoever. A real virus warning will link you to a page on Norton, for example, which contains specific, dated details of a virus threat and how to get rid of the virus. And it'll never tell you to email everyone you know about it - that's usually another way to recognise that it's a hoax: they're always worded in such a way as to try to induce mass panic.
