The word spoof means to falsify, hoax or deceive. A spoofed email is intentionally altered by the sender to imply that it is coming from a legitimate source such as a bank, company, friend or an online store. The sender will alter the email with a "letterhead" look to imply someone else is trying to contact you. In many cases the spoofed email is a form of phishing or (con man) attack. In other situations, spoofing is a way of dishonestly marketing an online service or trying to sell you a bogus product. Investigate before you click on that email. Opening it may do more harm than you are able to undo. When in doubt, delete the e-mail. Also, refrain from using the "reply all" option in your emails, and install a good anti-virus program.
