Browser hijacking Some adware uses Sear4m.xyz to cause a user to click on Sear4m.xyz ads. Once Sear4m.xyz is installed, it changes the default DNS settings of browsers like Mozilla Firefox, Google Chrome, and Internet explorer, and often redirect to various fake websites which are often laiden with viruses. Searchassist is a browser hijacker which piggybacks on other downloads from untrusted websites. It will change the new tab homepage to searchassist.net and opens searchassist on browser start-up. It is stubborn, and if not uninstalled, will repeatedly change the browser tabs and homepage settings. It works with Firefox, Safari, Chrome, and Internet Explorer, though
Usage share of web browsers According to StatCounter, , Chrome is the most popular browser on phones (or phones plus tablets). For tablet only browsing, Safari on iPad has 58.8% share, followed by Chrome, which inherited its engine and web standard support; Safari is not available for Android. When counting across all platforms, Chrome is the most popular, and if only desktop platforms are counted, it has more than half of that market. No desktop browser has had a clear majority for a more than a decade, since Internet Explorer lost it, with Netscape once holding the lead before that. Other statistics/analysts show similar numbers.
