Updated Jul 23, 2006

W32.Mydoom.AX@mm is a mass-mailing worm that may use its own SMTP engine to send emails to infect other computers. When W32.Mydoom.AX@mm infects your computer, it may gather email addresses from your Windows Address Book and email these people attachments infected with W32.Mydoom.AX@mm. Once your system is infected, W32.Mydoom.AX@mm may automatically download a trojan onto your PC.

W32.Mydoom.AX@mm’s file attachment may have an extension of .bat, .cmd, .com, .exe, .pif, .scr, or .zip, and the infected message may have one of the following subjects:

hello
hi
error
status
test

delivery failed
Message could not be delivered
Mail System Error – Returned Mail
Delivery reports about your e-mail
Returned mail: see transcript for details
Returned mail: Data format error delivered.

The email’s content may be:
