Information about the original VBS/LoveLetter.A is available at:
http://www.F-Secure.com/v-descs/love.shtml
This variant spreads in e-mail messages with the following content:
Subject: Yeah, Yeah another time to DEATH...
Body: This is the Killer for VBS.LOVE-LETTER.WORM.
Attachment: Vir-Killer.vbs
VBS/LoveLetter.Q deletes all files with the extension ".zip" or
".rar". It also hides all files with the extension ".asm" or ".pas".
After the original file has been deleted or hidden, the worm creates a
copy of itself using the original filename and an additional extension
of ".vbs".
This variant does not spread itself via mIRC.
