WHAT IS A SPYWARE ? WHAT IS A COMPUTER SPYWARE ?

WHAT IS SPYWARE : Spyware is a type of malware (just like detective or malicious software) installed on computers that collects information about users without their knowledge. The presence of spyware is typically hidden from the user and can be difficult to detect. Spyware is often secretly installed on a user's personal computer without their knowledge. However, some spyware such as keyloggers may be installed by the owner of a shared, corporate, or public computer on purpose in order to intentionally monitor users.
While the term spyware suggests software that monitors a user's computing, the functions of spyware can extend beyond simple monitoring. Spyware can collect almost any type of data, including personal information like Internet surfing habits, user logins, and bank or credit account information. Spyware can also interfere with user control of a computer by installing additional software or redirecting Web browsers. Some spyware can change computer settings, resulting in slow Internet connection speeds, un-authorized changes in browser settings or functionality of other software.
Sometimes, spyware is included along with genuine software, and may come from an official software vendor. In an attempt to increase the understanding of spyware, a more formal classification of its included software types is provided by the term privacy-invasive software. In response to the emergence of spyware, a small industry has sprung up dealing in anti-spyware software. Running anti-spyware software has become a widely recognized element of computer security practices for computers, especially those running Microsoft Windows. A number of jurisdictions have passed anti-spyware laws, which usually target any software that is surreptitiously installed to control a user's computer.

In Other Words : Any software that covertly gathers user information through the user's Internet connection without his or her knowledge, usually for advertising purposes. Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet; however, it should be noted that the majority of shareware and freeware applications do not come with spyware. Once installed, the spyware monitors user activity on the Internet and transmits that information in the background to someone else. Spyware can also gather information about e-mail addresses and even passwords and credit card numbers.
Spyware is similar to a Trojan horse in that users unwittingly install the product when they install something else. A common way to become a victim of spyware is to download certain peer-to-peer file swapping products that are available today.
Aside from the questions of ethics and privacy, spyware steals from the user by using the computer's memory resources and also by eating bandwidth as it sends information back to the spyware's home base via the user's Internet connection. Because spyware is using memory and system resources, the applications running in the background can lead to system crashes or general system instability.

They're both infections that can damage your computer, but the goals of the authors, techniques and damage they can do are very different. Learn how to tell them apart. First of a series on anti-spyware for the consumer and enterprise.
