Attachment

E-mail attachmentWhen referring to e-mail, an attachment is a file sent with the an e-mail message. An attachment can be a picture, a word document, a movie, a sound file, an excel document, or any other file that requires another program to open it.

In addition to the files mentioned above, attachments may also include computer viruses, Trojans, worms, or other malware. Unless you were expecting an attachment from the user sending you the e-mail, we suggest not open the attachment, even if it is an associate sending the e-mail. Viruses and worms can use address books to help spread the virus and make it appear to be a valid e-mail.
