The data that you pay for should be used by you and you only. But many a times it happens that some other parties are able to gain access to your router and exploit your data. Norton Blocking WiFi helps you counter that threat. You can switch it on from the user panel of the program. It will not only help you with saving your data but also lowering your data usage charge at the end of the month. Call the Norton customer support at +18555583999 to know more about the program and how you can use it to your benefit.
