Scan an item with Windows Security


Windows Security (or Windows Defender Security Center in previous versions of Windows 10) enables you to scan specific files and folders to make sure that they're safe. You'll be notified immediately if any threats are found.

  • To scan specific files or folders, right-click the ones you want, and then select Scan with Windows Defender. Or, go to Start  > Settings  > Update & Security  > Windows Security > Virus & threat protecton > Scan options (or Run a new advanced scan in previous versions of Windows 10) > Custom scan > Scan now, and select the file or folder you want to scan.
  • To turn on Windows Defender Antivirus in Windows Security, go to Start  > Settings  > Update & Security  > Windows Security > Virus & threat protection. Then, select Manage settings (or Virus & threat protection settings in previous versions of Windows 10} and switch Real-time protection to On. Windows Defender Antivirus will then automatically turn on. If you're running Windows 10 for Enterprise, turn on Windows Defender Antivirus by uninstalling all of your existing antivirus programs.
