Adware Spyware: Not As Innocent As It Looks!Free! - Shouts out a brightly colored advertisement on your screen, grabbing your attention. How often has it happened that you have been surfing the net, minding your own business when suddenly you are inundated with a barrage of pop-up advertisements advertising goods or services. The colorful advertisements are carefully designed to lure you into clicking them and ending up at an internet site you never even knew existed a few moments ago. What you are looking at is a specialized form of Spyware called Adware Spyware. In general terms, Adware spyware is any program that displays advertisements to a user possibly with or without the approval of the user. These can be categorized into two broad categories. First is a form that displays advertisements as a part of performing some user service. For instance many services waive off the registration fees in exchange for user permission to display advertisements, namely Eudora Mail Client. This is done with user consent and hence is not considered malicious. Another form is the one which can cause harm. A variant of this form spies on your activity on the internet, including the sites that you visit, links you click on and your areas of interest. Once it has acquired the information, it displays relevant advertisement that matches your area of interest. For example you are browsing articles about a computer peripheral, say a particular printer. The program spies on this activity and reports it back to the site which then displays advertisements for various printers with a link leading to a site that sells that particular printer. Now you must be wondering how it is advantageous to the site displaying the advertisement. Depending upon the number of people that visit the site selling the printers, the site displaying the advertisements will be paid a certain amount of revenue. This calculation is made depending upon the number of clicks or more technically known as the number of impressions. The greater the number of impressions, the more the revenue to the site displaying the advertisements.
