Short for fear, uncertainty, and doubt, FUD is a term that describes advertising or information that causes fear, uncertainty, or doubt by the person viewing the advertising.

For example, a person or company may advertise that because a product or service is free, it must not be as good as something that is not free. Another example is an advertisement saying your computer is infected with a virus and needs to be cleaned without actually even looking at your computer.
