Threat description

Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.

Variant:SSIWG.A@mm
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:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
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 ? Attachment: Y072QWV.VBS
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.
