Brief Description 

    

Loveletter.BJ is a worm that arrives in a message that aims to trick users into thinking they have received a love letter.

It spreads very rapidly by:

  • Sending e-mail messages with the subject ILOVEYOU with an attachment called LOVE-LETTER-FOR-YOU.TXT.VBS.
  • Automatically sending e-mail messages with the attachment LOVE-LETTER-FOR-YOU.HTM through IRC.

Whenever Loveletter.BJ infects a computer, it automatically sends itself out to all the contacts in the Address Book.

This virus has very damaging effects:

  • It deletes the content of files with VBSVBE, JS, JSE, CSS, WSH, SCT, HTA, JPG, JPEG, MP3 and MP2 extensions.
  • It steals confidential information from the affected computer and sends it to the virus writer. This could have particularly serious consequences for corporate networks.

Visible Symptoms 

    

A clear indication that you have received Loveletter.BJ is an e-mail with the following characteristics:

  • Subject:
    ILOVEYOU
  • Message:
    kindly check the attached LOVELETTER coming from me
  • Attachments:
    LOVE-LETTER-FOR-YOU.TXT.VBS

Another warning sign is a file called LOVE-LETTER-FOR-YOU.HTM sent through IRC.
