When VBS/SSIWG.A@mm is executed, it copies itself to the Windows
System directory as "Y072QWV.VBS". This file is also set to be
executed in each system startup via following registry key:
Next the worm copies itself to the root of each network drive, and
sends itself to all recipients in all address books using Outlook. Messages
that VBS/SSIWG.A sends have the following characterstics:
Subject: I'am missing U
Body: Could u remember me ?
Note: The name of the attachment can be other that "Y072QWV.VBS".
The worm uses a counter in the registry, so the mass mailing will
happen only every 20th run.
