1stBrowser is yet another potentially unwanted application which imitates the traits of Google Chrome and is actually the shameless copy of it. Once installed, 1stBrowser may add certain unwanted icons to your Desktop and set itself as your default browser. It will hijack your home page and default search engine settings. Finally, when you attempt to open Internet Explorer or any other decent browser to which you are accustomed, 1stBrowser will appear instead of it.
