Spyware

Before we start talk about spyware, it is very much necessary to know meaning of the term. Spyware is something that invites itself and takes up place on a computer, generally uninvited guest, which can inform on the behavior, action and preferences of the computer’s users, or reveal some secret information with reference to data stored on a computer. In other words, it can also be defined as, it spots on what the computer is intended for and probably for what it holds, to report on its findings to outsiders.

“Spyware is any technology that aids in gathering information about a person or organization without their knowledge. On the Internet (where it is sometimes called a spybot or tracking software), spyware is programming that is put in someone’s computer to secretly gather information about the user and relay it to advertisers or other interested parties. Spyware can get in a computer as a software virus or as the result of installing a new program. Data collecting programs that are installed with the user’s knowledge are not considered to be spyware if the user fully understands what data is being collected and with whom it is being shared. However, spyware is often installed without the user’s consent, as a drive-by download, or as the result of clicking some option in a deceptive pop-up window.

The cookie is a well-known mechanism for storing information about an Internet user on their own computer. However, the existence of cookies and their use is generally not concealed from users, who can also disallow access to cookie information. Nevertheless, to the extent that a Web site stores information about you in a cookie that you don’t know about, the cookie mechanism could be considered a form of spyware.”

By considering these different meaning, we can conclude some important points such as:

• Collect information about the user with his/her permission
• With no user’s knowledge, it might be operated to third parties.
• It might occasionally alter the behavior of a user’s computer without user’s permission.
