Yappyz is an adware application that is available for Windows XP/Vista/7/8 created and developed by SIEN. Typically, users might find Yappyz bundled with other free apps or download it themselves at their official website at yappyz.com. At first glance, adware-laced apps such as Yappyz may seem like a useful software to use, but in reality, they are monetization platforms. When you check the official website of Yappyz, you may notice that users are lured into downloading the software by providing a variety of online games that are free to play. However, adware-supported software like Yappyz is always with strings attached, so do not be surprised by the abundance of ads displayed by Yappyz. In addition, ads by Yappyz are recommended not to be clicked as they might cause other unwanted applications to be installed.
