“Spyware is a type of malware that can be installed on computers, and which collects small pieces of information about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. Sometimes, however, spywares such as key loggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users.” http://en.wikipedia.org/wiki/Spyware
