Removal

Automatic action

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

Suspect a file is incorrectly detected (a False Positive)?

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note You need administrative rights to change the settings.

Technical Details


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.
