Trojan Horse

VBS.Zeichen.A is a Trojan horse written in Visual Basic Script (VBS). It pretends to be a script that obtains URLs to the sites with porno-related contents. When executed, it appends malicious commands to the C:\Autoexec.bat and shuts down Windows. After the computer is restarted, the commands that were added to the Autoexec.bat file perform a hidden format of drives C and D without prompting and without the ability to unformat. The malicious payload works only under Windows 95, 98, and Me.
