What is OptimizationTool?

OptimizationTool is a deceptive application that may get on your Mac and corrupt browser settings so that a user is forced to carry out all searches via a new custom search engine. OptimizationTool replaces the primary search provider of the browser with a fake one in order to provide users with altered results. Furthermore, it will fill your system with a huge amount of diverse advertising (pop-ups, video/audio ads, coupons, best deals, etc.) as well as constant redirects to affiliate websites. It can initiate the automatic download and installation of other unwanted programs. The only way to avoid such a scenario is to completely remove OptimizationTool from your device. You should be able to do this without too many troubles by following our instructions below,
