The Melissa virus was a mass-mailing macro virus released on or around March 26, 1999. As it was not a standalone program, it was not classified as a worm. It targeted Microsoft Word and Outlook-based systems, and created considerable network traffic. The virus would infect computers via Email, the email being titled "Important Message From", followed by the current username. Upon clicking the message, the body would read: "Here's that document you asked for. Don't show anyone else ;)." Attached was a Word document titled list.doc containing a list of pornographic sites and accompanying logins for each. It would then mass mail itself to the first 50 people in the user's contact list and then disable multiple safeguard features on Microsoft Word and Microsoft Outlook.
