What are Peiynu pop-ups?

Peiynu popups are a result of adware action. Adware is a sort of malware that presents you the pay-per-view of pay-per-click advertisements, which creates a major amount of income for adware suppliers. These promotions might include explicit content, or have a web link to malevolent content/website, because adware maintainers have no purpose to check the goodness of the web content they are going to reveal – their single target is money.

Pop-up marketing itself is an excellent, cheap and also very efficient advertising instrument¹. It allows the seller to link the buyers’ interest to their website, as well as the customers to receive the dynamic updates on the goods they want to purchase. When the customer will get a pop-up alert that the TV set he wishes to buy is offered at the online shop he/she checked out previously with a 15% discount, one will undoubtedly use this chance and get it. Taking into consideration the extremely small cost for the popups and their targeting, such a marketing instrument is a favorite thing among the marketing departments of big online stores.

Nonetheless, such a successful strategy could not be missed by virus developers.

A lion’s part of this computer virus incidents is after the freeware or cracked programs, that are distributed on the peering networks. Freeware may also be downloaded from the official site, and the adware is provided as a legal bundled program.

There is no need to blame yourself. A number of people regularly utilize the unreliable programs from untrusted sources: abandonware, a wide range of tools that are free, or even hacked programs. Every one of these kinds of applications are unsafe, since it is very easy to integrate a Peiynu malware under the cover of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Peiynu popup virus can additionally be concealed in the promotion somewhere on the unusual web page. Such web pages are generally full of bright and blinking ads, and their owners typically permit any kind of promotions to be posted on their web page. Hence, clicking such banners is a shot in the dark: only the ad provider realizes what will happen when you press this advertisement. Besides some “light” viruses, like adware or unwanted programs, you can also receive something a lot more damaging, like ransomware or coin miner; the large share of coin miners circulation is exactly after the malicious promotions.

Distracting is not the only problem – pop-ups may display you the advertisements, where you are offered to get another unknown program, or “a effective security tool”. Scareware is often spread under the last motto. Potentially undesirable applications, in turn, may have spyware functionality. And it is quite hard to distinguish the unwanted app from a good one, if you don’t know the exact names. Besides the potentially unwanted programs and dubious antiviruses, popup-related banners are also used as a spreading method by various trojan viruses, for example – coin miners. The consequences of activity of such malware is 100% unwanted, and can cost you hundreds or even thousands of dollars. And even if you are not tapping these banners, they can be clicked by whoever who also uses your PC – parents, children, spouse, etc. So the situation can become much more serious, and it will be much harder to solve it without information loss.
