When referring to e-mail, an attachment is a file sent with an e-mail message. An attachment can be a picture, Microsoft Word document, movie, sound file, Excel spreadsheet, or any other file.

Are attachments safe to open?

Attachments may also include computer viruses, trojans, worms, or other malware. Unless you were expecting an attachment from the person sending you an e-mail, we suggest not opening the attachment even if it’s from someone you know. Viruses and worms can use address books to help spread the virus and make the e-mail that carries the virus appear to be valid.
