This Trojan drops and then executes a mass-mailing, malicious Visual Basic Script (VBScript) file. The VBS malware, which is detected by Trend Micro as VBS_SMALL.J, propagates via email using Microsoft Outlook.

A version of this Trojan connects affected systems to an adult Web site where it downloads an adult program.
