Worm/Virus are on the Prowl - Are You Prepared for W32.Netsky.B

by Symantec and Virtual Tech, Inc.

W32.Netsky.B 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.

Symantec Security Response has developed a removal tool to clean the infections of W32.Netsky.B@mm.
