Windows 10 is safer and more secure thanks to Windows Defender and Windows Firewall.
When you start Windows 10 for the first time, Windows Defender works to help protect your PC by scanning for malicious or unwanted software.
Windows Defender uses real-time protection to scan everything you download or run on your PC.
To scan specific files or folders, select them, then right-click (or press and hold) and choose Scan with Windows Defender. If Windows Defender finds anything malicious, it notifies you in the app and recommends what you should do next to keep your PC safe.
Windows Firewall filters the information coming into your PC from the Internet, blocking potentially harmful programs. To turn it off:
Select the Startbutton, then select Windows System > Control Panel.
Select System and Security > Windows Firewall > Turn Windows Firewall on or off > pick the networks you want to change settings for > OK.
If your PC is connected to a network, you might not be able to change your Windows Firewall settings because of network policies. Contact your administrator for more info.
To turn off real-time protection temporarily:
Select the Startbutton, then select Settings > Update & security > Windows Defender .
Turn off Real-time protection.
Windows Defender automatically turns off if you install another antivirus app.
