If this program has found its way into your Chrome, Safari, Firefox or other similar browsers, then you will likely have experienced one or more of the following symptoms. For example, applications of this kind tend to alter the browser homepage and/or introduce a new default search engine. In addition, they may install new toolbars and add-ons in the affected browsing program. And the added components are sure to cause a drastic increase in the number of observed online ads be they in the form or popups, banners or other advertising materials.

Page redirects are another very common occurrence that tends to go hand-in-hand with a browser hijacker infection. If you have come face to face with these, they will simply just load a new page URL either in your existing tab or open a new one and load it there. All of this is beyond annoying and more than enough reason for anyone to want to dispose of Horizon Centric immediately. And if that sentiment resonates with you, then below you will find just the remedy for your problem. We have compiled a simple-to-follow removal guide that will walk you through the steps necessary to remove Horizon Centric.
