In general, spyware is any technology that aids in gathering information about a person or organization without their knowledge.
Internet advertising (adware) has been criticized for occasionally including code that tracks a user's personal information and passes it on to third parties without the user's authorization or knowledge. This practice has been dubbed spyware and has prompted an outcry from computer security and privacy advocates, including the Electronic Privacy Information Center.

Noted privacy software expert Steve Gibson of Gibson Research explains:"Spyware is any software (that) employs a user's Internet connection in the background (the so-called 'back channel') without their knowledge or explicit permission. Silent background use of an Internet 'back channel' connection must be preceded by a complete and truthful disclosure of proposed back channel usage, followed by the receipt of explicit,informed consent for such use. Any software communicating across the Internet absent of these elements is guilty of information theft and is properly and rightfully termed: Spyware."
