HoroscopeZone, as its name suggests, will supposedly provide easy access to daily horoscope readings. However, it has been found to be a browser hijacker that will attempt to change your homepage and redirect your browser search towards a fake one. Once it does, search results will send you to malicious websites to get money from you or infect your computer further. It may also monitor your browsing history, show unwanted ads, and prevent you from changing your settings back.
HoroscopeZone is usually installed through bundled software without you knowing. Remove it immediately.
