This homepage hijacker is bundled with freeware to promote NationZoom Search and to make money using advertisements within the search results. Once this NationZoom browser hijacker is installed on your computer, the default search engine and homepage for Internet Explorer, Google Chrome or Mozilla Firefox is replaced with NationZoom. This NationZoom homepage is not malicious process itself and may not be called a virus, but it does change security settings within your favorite browser and is distributed by freeware. NationZoom also hijacks the shortcut of your favorite browser and adds a extra nationzoom.com argument behind the executable. By doing this hijacking the nationzoom.com website always opens when you open the browser, even as you replaced your default homepage with a website of your choice. It’s a very nifty and nasty method of forcing to drive web-traffic to there website.
Please be aware what you install on your computer. The NationZoom browser hijacker is most likely installed by the computer user itself because it’s offered during the installation process.
