I have received the email, unfortunatly nothing was attached for me to scan/test. However, based on the file name and infection vector, I preliminarily would guess you have Backdoor.Win32.IRCBot.apd, Discovered on November 11th, 2007. Protection is currently available for this threat by Kaspersky AntiVirus. However, to ensure a 100% diagnosis, I do need the file.
