F‑Secure Internet Security’s anti­virus scanner helps you identify viruses and other malware that can pose a threat to you and your devices. Internet Security’s real-time anti­virus scanner checks all files when they are accessed and blocks ones that contain malware. The harmful file is then quarantined before it can cause any harm. In addition to a real-time scanner, F‑Secure Internet Security lets you run a manual virus scan for checking for potentially harmful files or unwanted applications that may be hiding on your device.
