Adware is a kind of malware that suggests you the pay-per-view of pay-per-click advertisements, which generates a significant volume of income for adware representatives.

Pop-up advertising itself is a very good, cheap and also very efficient marketing instrument¹. It allows the vendor to attach the buyers’ interest to their site, as well as the customers to receive the dynamic updates on the goods they want to purchase. When the customer will get a pop-up notification that the TV set he likes to buy is available at the online store he/she saw earlier with a 15% price cut, one will definitely use this possibility and purchase it. Considering the incredibly low price for the popups and their targeting, such a marketing instrument is a favorite thing among the advertising teams of big online retail stores.
