Internet Explorer comes with a strong spyware and adware blocker already turned on so that you can enjoy a safe, uninterrupted browsing experience. These features will make your browsing experience free of ads and your movement online cannot be tracked by unknown sources.
If you have another browser and want to use that occasionally, you can do so by simply opening the browser from the desktop shortcut icon or from the start menu.
