W32.Netsky@mm

W32.Netsky@mm is a mass-mailing worm that uses its own SMTP engine to send itself to the email addresses it finds when scanning the hard drives and mapped drives. This worm also searches drives C through Z for the folder names containing "Share" or "Sharing," and then copies itself to those folders.

The "From" and attachment names of the email vary.
