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:FriendMess.A
The email message that this worm sends looks like this:
Subject: FRIEND MESSAGE Body: A real friend send this message to you. Attachment: FRIEND_MESSAGE.TXT.vbs
If the user executes the attachment, the worm copies itself to the Windows System directory as "FRIEND_MESSAGE.TXT.vbs".
After that, it overwrites autoexec.bat so that the next time the machine is rebooted it will try to delete all files from the Windows directory, from the Windows System directory and from the Temporary directory. This payload will not work in NT.
Then it shows a message box with the following text:
If you receive this message remember forever: A precious friend in all the world like only you! So think that!
Then the worm starts Outlook application in order to send itself via email to all addresses in all address books. The worm adds a marker in the registry for each address so that the email message is sent only once to each recipient.
