MS Windows 10 has enhanced its security design. It has a built-in component: Windows Security, which provides the latest antivirus protection. To ensure Windows Security works effectively, you should have to:
  • Keep your Windows updating continually;
  • Set Windows Security in the right ways.
1. Updating Windows
Updating is a critical job to keep your computer safe. One reason is any software has vulnerabilities that need to be fixed immediately as long as researchers get them. Otherwise, hackers or cybercriminals will have a chance to exploit them. Besides, we may see new malware or computer virus every day, so Windows Security need to maintain its virus bank or even sharpen its recognize algorithm from time to time.

Therefore, updating Windows is the key to run a safe and healthy computer. Fortunately, updating Windows usually doesn't cost you much extra job. As long as you set a computer in the right updating mode, it will do automatically.

You can view updating as following picture. The updates are downloaded to help keep your device safe and protect it from threats.

  • Virus & threat protection.
  • Account protection.
  • Firewall & network protection.
  • App & browser control.
  • Device security, performance & health.
  • Family options.
3. Windows Defender Antivirus
Windows 10 has a built-in antivirus tool. After you start Windows 10, it continually scans for malware, viruses, and security threats. Its integrated antivirus program called Windows Defender Antivirus.

If you have a third-party antivirus app installed and turned on, Windows 10 will turn off automatically. If you uninstall the other app, Windows Defender Antivirus runs automatically.

It means that Windows 10 already includes an antivirus app at the computer. Even if you don't buy any third-party security software, your Windows 10 are still safe as long as your computer keeps updating software and Windows Defender Antivirus on.

Windows Security updates you about antivirus protection by showing:
  • When the last scan runs.
  • When the last updated-definitions that Windows Security uses is.

  • Green means the setting is sufficient to protect your device.
  • Yellow means there is a safety recommendation for you.
  • Red is a warning that something needs your action.
4. Scan manually
You can scan file, folder, or device on demand by the built-in Windows Security component.

For a specific file or folder, you can right-click it in File Explorer, then select Scan with Windows Defender.To get malware or virus on a device, you should run a quick scan, which is much faster than running a full scan on all your files and folders.

Run a quick scan in Windows Security is by:

Start > Settings > Update & Security > Windows Security > Virus & threat protection

Then, open Windows Security settings, under Current threats, select Quick scan. If you don't find any urgent issues, you may want to check your device more thoroughly.

If you want to run an advanced scan in Windows Security, under Current threats, select Scan options:
  • Full scan (on your device)
  • Custom scan (scan specific files or folders)
Besides, you can add Windows Defender to the scheduled task list; then, it can scan at a specific time. Sometimes you may need to stop running real-time protection. The main reason here is to let the computer focus on some particular tasks. While real-time protection is off, Windows Defender won't scan threats anymore. However, real-time protection will soon turn on automatically unless you arrange other security mechanism to replace.
