Removal
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.
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 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:VBSWG.X
This is an encrypted worm generated with VBSWG virus kit. It is similar to the widely spread worm at February 2001 - VBS/Onthefly (also known as Anna Kournikova worm).
VBSWG.X worm spreads using Outlook Application. It sends messages with the following content:
Subject: Homepage Body: You've got to see this page! It's really cool ;O) Attachment: homepage.HTML.vbs
When the attached file is executed, the worm will send (mass mail) itself to each recipient in every address book. Then the worm tries to hide the mass mailing. It deletes all messages from Inbox and Deleted Items folders which contain a subject 'Homepage'. To mark that the mass mailing has been done, VBSWG.X adds a registry key:
HKCU\software\An\mailed
After that, depending on a random number, the worm attempts to open one of four x-rated web pages. However, the mass-mailing part of the code generates much more serious consequences, including overloading email servers and public relation problems.
