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.

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.
