A new variation of a recent virus is on the loose after the aftermath of the W32.Beagle.B@mm mass-mailing worm.
W32.Netsky.B@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 folder names containing "Share" or "Sharing," and then copies itself to those folders.
The Subject, Body, and email attachment vary.
