Yontoo Layers Client (aka Yontoo) is a platform for building applications that modifies the way specific webpages look. The application is distributed as browser extension and might display advertisements served through Yontoo and not original page. Thus we classify this application as adware and potentially unwanted program. One of the “famous” applications using Yontoo platform is Pagerage, which modifies Facebook.
Yontoo installs a browser extension. It can affect any Internet browser, whether you use Internet Explorer, Chrome or Firefox. Some users do not know how they get this program installed, although it is downloaded and executed to the system manually usually. In the most cases it came inside bundled with other software (Video converters, MP3 players, etc.) that computer users can download from third-party websites. The application might have been installed by kids too.
On itself, Yontoo Layers Client is not dangerous. However, the applications, made using this platform, range from useless to annoying. At the best, you will see some pages differently than intended by their creators. At the worst, you will get more advertisements and loose some privacy because of content served from other sources. Yontoo is a tool to build advertisement programs.
We recommend uninstalling any application modifying the way pages look that was installed without your consent. This includes all of Yontoo applications. Anti-malware programs like Spybot S&D and Spyhunter detect and remove such browser modifying applications if they can not be uninstalled normally. Many of these programs can be removed with Adwcleaner as well, though you might wish to scan with broader anti-malware tools to confirm that Yontoo infection is not a by-product of trojan attack.
