What is UltraEngine?

UltraEngine is a rogue browser extension that is often called a browser redirect virus. The browser hijacker usually gets on users’ devices together with freeware programs as an optional component. Following infiltration, it changes the default search engine, homepage, and new tab URL settings so that all your search queries will be redirected to Yahoo.com. The problem is that you can’t replace it because the hijacker blocks all your attempts. Although Yahoo is a legitimate search engine, users may notice irrelevant search results and numerous ad links. Also, the hijacker tracks a user’s browsing activities and collects data such as passwords, search queries, browsing history, cookies, technical information, and other data. Therefore, we strongly recommend you uninstall the browser hijacker and remove UltraEngine from your Mac device.
