How to protect your Windows 10 PC

Gilt für: Windows 10Security

Turn Windows Security on or off

  • When you get a new device and start up Windows 10 for the first time, the antivirus protection that comes installed with the device is your default security app. However, Windows Security is pre-installed and ready for you to use at any time.
  • If you want to use Windows Security, uninstall all of your other antivirus programs and Windows Security will automatically turn on. You may be asked to restart your device. (Note that in previous versions of Windows 10, Windows Security is called Windows Defender Security Center.)

Where's Security Essentials?

If you have Windows 10, you can't get Microsoft Security Essentials. But you don't need it, because you already have Windows Security, which provides the same level of protection.

  • In the search box, type Windows Security.
  • In the list of results, select Windows Security. You'll be able to check your computer and your level of virus protection.

Updating Windows Security

Windows Update downloads updates for Windows Security automatically to help keep your device safe and protect it from attacks.
