From: firstname.lastname@example.org 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.

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".
