Brief Description 

    

Trile.B is a worm that infects a large number of files on infected computers by copying itself to the beginning of them and ends active processes belonging to antivirus and security programs.

This worm mainly spreads via e-mail and the P2P (peer to peer) file sharing programs KaZaA and Shareaza. When it spreads via e-mail, Trile.B reaches computers in a message that includes an attached file with variable characteristics. For a list of these files click here.

When it has infected a computer, Trile.B sends itself out to all the contacts in the Address Book in Outlook.

Visible Symptoms 

    

Trile.B is difficult to recognize, as does not display any warnings or messages that indicate that it has infected a computer.  However, after infecting a computer, Trile.B displays a variable error message.
