When turned on, F‑Secure Internet Security’s Browsing Protection blocks harmful web­sites and stops them from causing harm to your device. Some harmful web­sites may seem safe on the outside, but can still contain suspicious and dangerous content. Browsing Protection stops you from accessing such spam sites or other web­sites that can down­load unwanted apps, illegal material or malware to your device. You can also manually block and allow sites with F‑Secure Internet Security and its Browsing Protection.
