Windows comes with a powerful, built-in protection system called Windows Security (formerly Windows Defender). It’s not just an antivirus — it’s a complete suite that protects your computer from viruses, ransomware, phishing, and other online threats.

The best part is, it runs quietly in the background. You don’t have to install anything extra. It updates automatically through Windows Update and keeps an eye on every file and download in real time.

To check your security status, type “Windows Security” in the Start menu. Inside, you’ll find different sections like Virus & Threat Protection, Firewall & Network Protection, and Device Performance & Health.

If you ever see a yellow or red warning, it means something needs attention — like an outdated virus definition or a disabled setting. Keeping everything green ensures your PC stays protected.

Windows Security has come a long way and, for most users, it’s all you really need to stay safe online.
