Pop-up advertising itself is a very good, low-priced and also really successful marketing instrument1. It makes it possible for the vendor to link the customers’ interest to their site, as well as the buyers to receive the dynamic updates on the goods they wish to buy. When the customer will receive a pop-up alert that the TV set he wishes to purchase is offered at the online store he/she visited previously with a 15% discount, one will certainly use this opportunity and get it. Taking into consideration the extremely low price for the popups and their targeting, such a promotion and marketing tool is a favourite thing among the advertising departments of big internet retail stores.

Potential to show the popup ads by force to the targets of malware attack is a perfect basis for malicious adjustments with the popup advertisements.

Besides some “light” viruses, like adware or unwanted programs, you may also receive something far more threatening, like ransomware or coin miner; the large share of coin miners circulation is exactly after the malicious advertisements.
