Pop-up promotions itself is an excellent, low-cost and also extremely productive marketing instrument¹. It makes it possible for the vendor to attach the customers’ attention to their site, as well as the customers to receive the dynamic updates on the goods they wish to purchase. When the customer will get a pop-up alert that the TV set he wishes to buy is offered at the online store he/she visited previously with a 15% price cut, one will definitely use this opportunity and buy it. Considering the exceptionally low cost for the popups and their targeting, such an advertising method is a much-loved thing amidst the marketing departments of big online stores.

However, such a successful plan could not be missed by malware developers.
