PUA.Yontoo is a potentially unwanted app that may install itself as a browser extension and display targeted advertised content. According to Symantec researchers, the adware app mainly targets Facebook for displaying ad content.

How Did PUA.Yontoo Get On My PC?
There are several ways by which this annoying PUP may have gotten into your PC. One of them is being redirected via another adware app to an add-to browser page. Another way that it may have gotten in your PC is by clicking on a random ad that contains such link. However, the most often case that such applications get into the computer is the bundling method. It is essentially an extremely successful money making scheme that involves attaching applications in the installers of other widely distributed free software, downloaded from freeware providing websites.
PUA.Yontoo What Does It Do?
Once added as an extension to your computer, Yontoo adware may begin to display various types of advertisements on your PC. The most common way to advertise to you is by obtaining your browsing information, such as click history, browsing history and search history. Based on that it may either modify site content (E.g., highlighted text with a hotlink to the ad page), display random pop-ups that sometimes may prove to be pretty annoying.
More to it than that, those advertisements often redirect the user to third-party websites. And any experienced user knows that these websites often lead to devilish sites. They often do various mindless tricks to con the user into either installing fake updates or give out their information. I mean, for you such cons may be like ‘Haha! Not me!’. But there are a lot of users who get tricked by these daily.
