Brief Description 

    

Zapchast.D is a Trojan that is created by certain variants of the Sdbot family.

Zapchast.D uses the commands contained in a script detected as W32/Sdbot.ftp, which is also created by some Sdbot variants, in order to download a file to the computer via FTP.

Afterwards, it runs the downloaded file, and then it deletes both Sdbot.ftp and itself from the computer.

Visible Symptoms 

    

Zapchast.D is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
