Pop-up marketing itself is a very good, affordable and also really efficient marketing instrument1. It enables the seller to attach the customers’ attention to their site, and the buyers to receive the dynamic updates on the goods they want to purchase. When the consumer will receive a pop-up notification that the TV set he wishes to purchase is provided at the online shop he/she saw earlier with a 15% discount, one will surely use this opportunity and purchase it. Taking into consideration the very low cost for the popups and their targeting, such a promotion and marketing instrument is a much-loved thing amidst the advertising departments of large internet sellers.

Nevertheless, such a profitable strategy could not be missed by malware developers.

A lion’s part of this virus cases is after the free software or cracked programs, that are spread on the peering networks. Free software can additionally be downloaded from the main web page, and the adware is supplied as a legal bundled program.

There is no need to blame yourself. A number of individuals regularly make use of the unreliable programs from untrusted sources: abandonware, various utilities that are free, and even hacked programs. Every one of these types of applications are dangerous, because it is extremely easy to include a Tei.ai malware under the cover of part of the license hacking script, or as a part of the self-made algoritm inside of the Windows optimization tool.

Tei.ai popup malware can likewise be hidden in the ad somewhere on the unusual web page. Such sites are in most cases loaded with bright and blinking ads, and their owners generally permit any type of promos to be posted on their web page. Hence, clicking on such banners is a shot in the dark: only the ad contractor realizes what will happen when you click this advertisement. Besides some “light” viruses, like adware or undesirable programs, you may also receive something a lot more risky, like ransomware or coin miner; the big share of coin miners circulation is exactly after the malicious advertisements.

Distracting is not the only effect – pop-up notifications can display you the promotions, where you are offered to get another dubious program, or “a amazing anti-malware tool”.

And it is very hard to distinguish the undesirable app from a legit one, if you don’t know the exact names. Besides the PUPs and pseudo antiviruses, popup-related promotions are also exploited as a spreading way by different trojan viruses, for instance – coin miners. The consequences of activity of such viruses is 100% unpleasant, and can cost you hundreds or even thousands of dollars. And even if you are not clicking these advertisements, they can be clicked by someone who also uses your personal computer – parents, children, spouse, etc. So the situation may become much more serious, and it will be much harder to deal with it without data and money loss.
