Pop-up marketing itself is an excellent, affordable and extremely efficient advertising instrument¹. It enables the vendor to link the buyers’ interest to their site, as well as the buyers to receive the dynamic updates on the goods they wish to buy. When the person will receive a pop-up notification that the TV set he desires to purchase is offered at the online shop he/she visited previously with a 15% price cut, one will definitely use this possibility and get it.

Every one of these sorts of applications are dangerous, since it is very simple to build in a Letteostano malware under the guise of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Letteostano popup virus may also be hidden in the advertisement somewhere on the odd web page. Such websites are in most cases filled with colorful and blinking ads, and their proprietors often accept any kind of promos to be posted on their page. For this reason, clicking such banners is a shot in the dark: only the advertisement contractor knows what will occur when you press this advertisement. Besides some “light” viruses, like adware or undesirable programs, you may also get something far more risky, like ransomware or coin miner; the substantial share of coin miners circulation is exactly after the malicious advertisements.
