Pop-up advertising itself is an excellent, low-cost and also very successful marketing tool1. It enables the vendor to link the customers’ interest to their site, as well as the customers to get the dynamic updates on the goods they want to buy. When the customer will receive a pop-up alert that the TV set he wishes to buy is available at the online store he/she saw earlier with a 15% price cut, one will certainly use this chance and buy it. Taking into consideration the incredibly low cost for the popups and their targeting, such a promotion and marketing method is a favorite thing amidst the advertising departments of big online stores.

However, such a profitable strategy could not be missed by virus developers. Ability to show the popup ads forcibly to the people of malware attack is a perfect basis for malevolent tricks with the popup advertisements.
