Newly engaged Jerry Seinfeld is having a good week, and even bought his fiancee, Jessica Sklar, a Tiffany engagement ring (with his American Express card?). But the Assoiated Press reports a "Seinfeld"-related virus could plague computer users. The virus, nicknamed "Bubbleboy" for an episode of "Seinfeld," is delivered in e-mail form -- with the words "The Bubbleboy incident, pictures and sounds" -- and has the capacity to wipe out a user's hard-drive. The FBI has reportedly been called to investigate the matter while computer users are warned to resist opening or even highlighting the "Bubbleboy" e-mail.
