Spyware: Malware that collects and transmits user information without their knowledge

Spyware is malware that collects some data, usually without the computer users' knowledge. Very often, this data is then sent over the internet to someone else. Very often, this is used for marketing. Spyware can also be used to steal data from computers. One kind is a keylogger which can see whatever you are typing. Keyloggers can steal important information like passwords that you type.

The best protection is to get a program that protects against spyware. However, many websites that claim to have them are actually spyware, not something to protect against it. This method of installing spyware is called a Trojan horse which looks like a normal program, but when it runs, it collects information to use against you. Spyware tracks your computer and uses some of the things on it. This includes your files, your downloads, and usernames/passwords for websites and programs. With this, the trojan operator can log into your accounts.

There are spyware applications that are designed to enable users to spy on themselves rather than others. This is called myware. The term myware has mainly been applied to software applications in three areas: social networking, marketing and time tracking.
