What are N04.biz pop-ups?

N04.biz popups are an outcome of adware action. Adware is a type of malware that shows you the pay-per-view of pay-per-click advertisements, which creates a substantial amount of earnings for adware suppliers. These ads might have sometimes shocking information, or have a link to malevolent content/website, due to the fact that adware maintainers have no reason to examine the goodness of the web content they are going to show – their single target is money.

Pop-up advertising itself is a very good, low-cost and also really productive advertising instrument¹. It enables the vendor to attach the buyers’ interest to their website, and the buyers to receive the dynamic updates on the goods they intend to buy. When the consumer will get a pop-up alert that the TV set he desires to buy is provided at the online shop he/she saw earlier with a 15% discount, one will undoubtedly use this possibility and purchase it. Considering the extremely low cost for the popups and their targeting, such an advertising instrument is a much-loved thing among the advertising teams of large internet sellers.

Nonetheless, such a successful plan could not be missed by virus creators. Potential to demonstrate the popup ads forcibly to the targets of malware invasion is a great basis for malevolent adjustments with the popup promotions.

A lion’s part of this computer virus incidents is after the free software or cracked programs, that are distributed on the peering networks.

There is no need to blame yourself. A huge amount of users regularly use the uncertain programs from untrusted providers: abandonware, various tools that are free of cost, or perhaps hacked programs. All of these sorts of programs are unsafe, since it is very simple to build in a N04.biz malware under the guise of part of the license hacking script, or as a part of the self-made algoritm inside of the Windows optimization tool.

N04.biz popup malware may also be hidden in the ad somewhere on the unusual site. Such sites are in most cases full of colorful and blinking ads, and their proprietors typically permit any kind of promos to be posted on their web page. Hence, clicking such banners is a shot in the dark: only the advertisement contractor realizes what will happen when you click this advertisement. Besides some “light” viruses, like adware or unwanted programs, you can also get something a lot more risky, like ransomware or coin miner; the substantial share of coin miners circulation is exactly after the malicious promotions.

Scareware is usually distributed 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 fake antiviruses, popup-related promotions are also chosen as a spreading way by different trojan viruses, for example – coin miners. The consequences of activity of such viruses is 100% unpleasant, and can cost you several hundreds of dollars. And even if you are not interacting with these banners, they can be clicked by whoever who also uses your PC – parents, children, spouse, etc. So the things may become much more serious, and it will be much harder to deal with it without information loss.
