The security software, Microsoft Defender, similarly uploads suspicious files to Microsoft to determine if they are malicious or not. However, some people consider this a privacy risk and do not want to upload their data to Microsoft.
By default, when Microsoft Defender scans a device for suspected malicious files, it uses the “auto-sample send” feature (sandboxing) to upload the files to Microsoft’s servers.
Microsoft’s cloud-based protection analyzes the files and if they are determined to be malicious, Microsoft Defender will quarantine them on the device.
When sending files, Microsoft Defender automatically uploads executables and scripts, but first warns the user when uploading files that may contain personal information such as documents
When “Windows Defender Antivirus” is turned on, it monitors the security status of the device.
Files that do not potentially contain user data will automatically be sent to Microsoft. However, if Windows Defender Antivirus attempts to send a file such as a document or spreadsheet that may contain personal information, you will be prompted for permission
