Computer users were today warned to beware of a fastspreading e-mail virus which promises a photograph of tennis star Anna Kournikova. The virus tempts users with the message: "Hi: Check This!", together with what appears to be a picture file labelled "AnnaKournikova.jpg.vbs".
But clicking on the file produces no picture. Instead, the virus e-mails itself to every address in the user's address book.
