The first question that we need to ask is, What is spyware? Wikipedia offers one of the best descriptions: "Spyware covers a broad category of malicious software designed to intercept or take partial control of a computer's operation without the informed consent of that machine's owner or legitimate user. While the term taken literally suggests software that surreptitiously monitors the user, it has come to refer more broadly to software that subverts the computer's operation for the benefit of a third party."
