An Email-Worm (also known as a mass-mailer or less commonly, an Internet worm) is a type of worm that distributes copies of itself in an infectious executable files attached to fake e-mail messages.
For representative examples of email-worms, see:
Email-worms typically depend on social engineering tactics to lure a user into opening and executing an e-mail attachment. As such, users can avoid infection by an email-worm by simply refusing to open any e-mail file attachments without first verifying its safety with the e-mail sender.
In some cases however, an infected attachment may contain an exploit that allows the e-mail worm to install and start automatically on the computer, without any user action. This is only possible if the e-mail client contains certain vulnerabilities.
Most worms nowadays include malicious routines (e.g.,password or data stealing), or carry viruses and backdoors inside them.
