What is UltraSystem

UltraSystem is a potentially unwanted application (PUA), that comes in form of extensions for Safari, Google Chrome, and Mozilla Firefox browsers on Mac systems. The app is classified as adware because it displays pop-up ads and unwanted advertisements, that do not belong to the sites you are browsing. Such UltraSystem advertisements may look differently: boxes with coupons, underlined words (in-text ads), pop-up ads, or banners. Also, UltraSystem can modify search engine and homepage settings, which can result in search redirects to doubtful websites. As an add-on, UltraSystem gets permissions to access your browser history and, what is more dangerous, sensitive information from web pages including passwords, phone numbers, and credit cards. This data can be used with bad intentions, and to avoid much more serious problems we advise you to remove UltraSystem as soon as possible. The following tutorial will assist you in this.
