Brief Description 

    

Backterra.A is a worm without destructive effects that spreads through the peer-to-peer (P2P) file sharing program eMule.

Backterra.A tricks the user into thinking that it is a key generator for computer applications and games.

Visible Symptoms 

    

Backterra.A is easy to recognize once it has reached the computer, as it displays the following messages on screen:

  • If the file sharing program eMule is not installed, it pretends to be a key generator:

  • If the user inserts any information in the form and pushes the button Make a key, Backterra.A displays an error message:

  • If eMule is installed on the affected computer but Backterra.A is unable to locate the file SHARE.DAT, it displays the error message above.
  • Finally, if eMule is installed and Backterra.A locates the file SHARE.DAT, it displays the error message and is ready to spread.
