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 email messages.
Email-Worm typically arrive as executable files attached to fake email messages.
Some mass mailers randomly compose the subjects and bodies of the messages from words and phrases carried in the worm's own code; other worms use content found in randomly selected files in the infected computer to compose the message. The name of the file attachment can be either random, or 'borrowed' from other files.
Many worms send themselves as attachments with double extension, for example .MPG.EXE or AVI.PIF. Often, a recipient will only notice the first extension listed and will try to open such attachments thinking, that they are multimedia files.
