Brief Description 

    

Music.A is a worm that is easy to recognize as it shows Christmas greetings messages on the affected computer’s screen.

It reaches computers in a file called MUSIC (with EXE, COM or ZIP extension) attached to an e-mail message with the following text:   Hi, just testing email using Merry Christmas Music file, you'll like it.

Music is not a dangerous worm as it does not have any destructive effects:

  • It displays several images on screen. 
  • It plays the tune We wish you a Merry Christmas.
  • It updates itself via the Internet.
  • It sends itself out to every address found in the Address Book.

The first symptom of Music.A is an e-mail message with the following characteristics:

  • Message: any of the following two texts:
    Hi, just testing email using Merry Christmas Music file, you'll like it.
    Hi, just testing email usingMerry Christmas Music file, not bad Music.
  • Attachments: Any of the following:
    MUSIC.EXE
    MUSIC.COM
    MUSIC.ZIP

  • The tune We wish you a Merry Christmas   is played though the computer’s speakers.
  • The following image is displayed on the screen:

  • When the music finishes, another window is displayed:
