Yontoo “Malware”


In the event that you’ve been infected with a program called Adware Yontoo, then your browser has probably become flooded with popups, banners, box messages and various other online ads by now. And it’s of little difference whether you use Chrome, Firefox, Edge or a different browser – most of the popular ones are all prone to such infections.

That’s not to say that you’re done for now. Much on the contrary, you can easily rid yourself of all the annoying and invasive ads that just never cease to appear. And as a matter of fact, we’ve prepared a very detailed yet simple removal guide, which will help you locate and delete all the necessary Adware Yontoo files from your system. However, before you head on to the removal guide, it is our sincerest recommendation that you continue reading the information within this article, so as to gain better insight into the nature of this program and adware in general. It will help you better recognize risks from now and potentially protect your PC from more dangerous programs.

What is Yontoo?

If you have a look at the word ‘adware’ it shouldn’t be too difficult to discern where it comes from. But we’ll break it down for you: adware basically means advertising software. You may have deduced as much from the many popups and banners that have started covering your screen since it appeared on your PC. So, the point of programs like Adware Yontoo is to generate as many ads as possible, so as to gain exposure for different products services. At the same time, these programs also help generate revenue for their developers. And this, in turn, happens typically when users click on the said online ads. Remuneration models like the famous Pay Per Click scheme are what ensures that this whole process works and benefits both sides: the people vested in getting their products and services promoted and the adware developers.

That’s why the ads are often so aggressive and intrusive. That’s also why sometimes attempting to close them results in new ones opening and other such annoying instances. But aside from that, the developers also employ a secret weapon, which you won’t notice unless you know of it. The thing is that programs like Adware Yontoo are often designed with the ability to look through your browsing history and analyze it. For example, they can take into consideration the type of websites you like to hang around most, as well as your latest online search requests. Furthermore, they can even monitor your social media activity and take note of the things you tend to like and share. All of this information combined allows the adware to determine which of its ads are likely to be more interesting to you. Then, based on the performed research, it will usually modify the display of ads, so as to match your preferences and potentially attract more of your clicks. In fact, you may have noticed this yourself if you pay attention to the ads.

But that’s not the scariest thing that can come as a result of Adware Yontoo’s presence on your machine. While it’s an invasive practice to say the least, it’s not necessarily a harmful one. But the adware’s ability to expose you to serious online threats like viruses, Trojans and ransomware is surely something worth considering. This can happen indirectly, as a result of the modifications that adware programs often initiate in your Registry. These modifications can subsequently make your system more vulnerable to external threats, and that’s all any virus or malicious program really needs to infect you. In addition, with so many ads constantly flooding your screen and you struggling to close them and just navigate the websites you need, you may run into the so-called malvertisements. These are fake ads used by hackers and cybercriminals for the distribution of their malicious scripts.

In order to avoid all that it’s best to simply remove the source of all the ads and the annoying changes to your system – Adware Yontoo. From now on you’d also best be more careful with the kind of programs you download. This adware likely came bundled with one of them and you installed it without realizing it. Also, be sure to always customize the installation of any new program, so as to not have to deal with such unpleasant surprises in the future.
