TabNav is a Potentially Unwanted Program (PUP), created by FlowSurf Apps. As a typical representative of the family of PUPs, TabNav offers very limited utility for the user. The tiny application provides a button on Google that should reportedly optimize the search speed. However, the majority of people don't find TabNav helpful as its presence leads to the creation of many ads. The adware promotes partner sites, which legitimacy cannot be confirmed. The user may notice that the popping up messages and banners are surprisingly accurate and attract his interest considerably. This happens because TabNav records the browsing history and monitors the searches in order to adjust the displayed content to the taste of the user. Keeping the PUP is not recommended as it unnecessarily slows down the browser and may trick the user into potentially harmful domains. In order to keep TabNav away, people should read the EULA of freeware and cancel the installation of suspicious elements. If the adware is already present, it can easily be removed by special security software.
