Yontoo Layers

Yontoo Layers Description

There have been many reports of computer systems showing constant advertisements due to a Yontoo adware infection. Although these kinds of applications are often installed with the full knowledge that they will display advertisements, ESG security analysts have also received reports of severe virus and Trojan infections contracted from advertisements that Yontoo displays. Basically, the Yontoo application will be installed as part of a requirement for installing an application known as PageRage, designed to overlay designs on top of Facebook's profile pages, in essence allowing computer users to customize and make more attractive their Facebook wall, profile and Timeline.

PageRage's manufacturers claim that Yontoo is a legitimate way of supporting their software, although it is up to computer users to decide whether the advertisements that Yontoo delivers to the computer system are worth being able to tweak the appearance of a Facebook profile. There are several reasons why Yontoo is a form of adware, although this kind of infection may be worth the risk for some computer users. The main issue of installing Yontoo on your computer is the fact that advertisements that Yontoo displays may lead to undesirable sites. Yontoo also has some behaviors that are not compatible with good applications acting in good faith. For example, Yontoo Adware has several tracking and data-recollection components that are embedded and may be difficult to disable, as well as the fact that Yontoo is not entirely honest about what Yontoo does when installed on the computer user's system. While Yontoo Layers is limited to your web browser and can be easily quarantined by most security applications, some of the advertisements that Yontoo displays contain questionable content.
