Melissa

Another virus that fired up the media was Melissa, a Word macrovirus.

When people received the host Word document via email andopened it, the virus sent a copy of itself to the first 50 people in the

victim's address book. Named after a topless dancer in Florida, the Melissa virus crashed

the email servers of corporations and governments in differentspots around the world.

The Computer Emergency Response Team, set up after RobertMorris mucked up the Internet with his worm in 1988, estimated thatthe virus hit 100,000 computers in its first weekend.

David L. Smith posted the infected file to an alt.sex usenet groupusing a stolen AOL account. Initially he entered a plea ofinnocence, but after being confronted with a maximum sentence of40 years in prison, he eventually pled guilty and received a much-reduced sentence.

Love You, Love Bug

By almost any measure, the so-called Love Bug was the mostdamaging and costly virus ever. I don't know who comes upwith these whack figures, but according to Reuters the bugcost the world $15 billion in lost productivity.

The Love Bug spread far faster than Melissa. Unlike Melissa,it would mail itself to everyone in your Outlook address book-- most of whom would probably be delighted to read abouthow you love them -- not just the first fifty. Moreover, it wouldgobble up certain media files stored on your hard drive.
