Technical Details



VBS/LoveLetter.G is similar to the original VBS/LoveLetter.A virus.

This variant sends a message that seems to originate from Symantec's support. This is not true. The message looks like the following:

Subject:    Virus ALERT!!!
    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 e-mail itself as an attachment.
    The subject line of the e-mail reads ILOVEYOU, with the
    attachment titled LOVE-LETTER-FOR-YOU.TXT.VBS. Once the
    attachment is opened, the virus replicates and sends an
    e-mail to all e-mail 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 e-mails with
    this subject line, even if the e-mail is from someone they
    know, as that is how the virus is spread.
    Symantec Corp. today announced availability of the virus
    definition to detect, repair and protect users against the
    VBS.LoveLetter.A virus.
    This definition is available now via Symantec's LiveUpdate
    and can also be downloaded from the following web sites:

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".
