The main purpose of Pogothere.xyz and other apps of its type is to make money through ads, by employing the well-known Pay-Per-Click ad Pay-Per-View models. To generate as much advertising revenue as possible through those models, Pogothere.xyz needs to show large numbers of ads and cause frequent page-redirects, which explains its rather invasive and aggressive behavior. The changes in the browser, too, are made to facilitate the advertising activities of the hijacker.  However, while all this may make the app annoying and unpleasant, the real security issue stems from the nature of the content that often gets promoted by hijackers. You see, there’s usually hardly any control over what gets advertised - it could be legitimate sites, but it could also be rogue pages with phishing elements embedded in it, or even malware-distributing sites filled with disguised Ransomware, Trojan Horse, and Spyware downloads. While you can try to avoid clicking on the spammed ads and immediately close any sites you may get redirected to, this is not a sustainable way of keeping your PC safe.  The only real solution to the Pogothere.xyz problem is to fully eliminate the rogue software and all data and settings related to it. Below, there’s a helpful guide that will show you the steps required to manually get rid of the hijacker, and there you will also find a professional removal software that specializes in eliminating undesirable hijackers and other forms of PUPs (potentially unwanted programs) that may not get detected by conventional antivirus programs. We recommend using both methods to ensure that the browser hijacker on your computer gets fully removed.
