Yontoo adware - how to eliminate Buzzdock ads from Google and deceptive ads from YouTube?

What is Yontoo?

Yontoo is a company that develops browser add-ons and web applications. Their products include web apps such as Best Video Downloader (a web app that allows users to download videos from YouTube), PageRage (an app that allows users to change Facebook layouts), EasyInline (an app that enables the highlighting of text and provides options to search across various popular resource sites), and many others. While the idea of enhancing your Internet browsing experience with various browser add-ons and plug-ins is valid, Yontoo apps are ad-supported and thus employ some deceptive methods to display them. For example, after installing Best Video Downloader, visitors to YouTube will notice that the ads no longer originate from Google - the Yontoo app overrides them with its own.

It is important to note that downloading YouTube videos in this manner does not comply with copyright law, and furthermore, ads shown within YouTube after installing Best Video Downloader app can compromise the security of your PC and your privacy. Some of these ads will request users to complete online forms in order to claim a scam prize. Dubious ads such as these could also result in the installation of unwanted applications or even malware.

When any Yontoo apps are installed on your Internet browsers, the displayed ads relating to searches no longer originate from Google. Yontoo overrides them with Buzzdock ads. Google is a reputable company, which spends a great deal of time and money to filter out ads that could harm your computer or invade your privacy. Note that it is not advisable to allow third party ads imposed in your browsers to replace original Google ads. If you have willingly installed Yontoo and are happy with the free services, then no action is necessary, however, be cautious when clicking ads displayed in YouTube and Google. If you are concerned about your computer's security and your own privacy, remove this app from your PC. Use the removal guide provided to help eliminate Yontoo from your computer.
