Windows 11 comes with a built-in antivirus that is known as Windows Security or Windows Defender. When this antivirus detects any suspicious files, it sends them to Microsoft server so that their security team can analyze and learn more about new threats. By default, Windows built-in antivirus automatically sends samples of suspicious files from your PC to Microsoft. However, there is a provision to stop sending the suspicious file to the Microsoft server. After preventing automatic sample submission to the server, you can still send them files, but manually.
