Summary

This variant of Email-Worm:VBS/Loveletter is distributed as an infectious email file attachment.

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.

 From: support@symantec.com

 Body: Dear Symantec customer, 	Symantec's AntiVirus Research Center began receiving

 reports regarding VBS.LoveLetter.A virus early morning on

 May 4, 2000 GMT.

 This worm appears to originate from the Asia Pacific

 region. Distribution of the virus is widespread and

 hundreds of thousands of machines are reported infected.

 The VBS.LoveLetter.A is an Internet worm that uses

 Microsoft Outlook to email itself as an attachment.

 The subject line of the email reads ILOVEYOU, with the

 attachment titled LOVE-LETTER-FOR-YOU.TXT.VBS. Once the

 attachment is opened, the virus replicates and sends an

 email to all email addresses listed in the address book.

 The virus also spreads itself via Internet relay chat and

 infects files on local and remote drives including files

 with extensions vbs, vbe, js, sje, css, wsh, sct, hta, jpg,

 jpeg, mp3, mp2.

 Users should exercise caution when opening emails with

 this subject line, even if the email is from someone they

 know, as that is how the virus is spread.

This variant changes the Internet Explorer start page to point to an adult site. The default search page is set to point to a hacker site.

The virus creates a new file with the same name for the files with the following extensions: ".js", ".jse", ".css", ".wsh", ".sct", ".hta", ".com" and ".bat", but using the extension ".vbs". The original file will be deleted. Since all ".com" files have been removed, the system cannot be restarted.

This variant does not attempt to download the "WIN-BUGSFIX.exe".
