Report suspicious software to Microsoft SpyNet

If you join the Microsoft SpyNet community, and if Windows Defender detects software on your computer that has not yet been classified for risks, you might be asked to send a sample of the software to Microsoft SpyNet for analysis. When you're prompted, Windows Defender displays a list of files that can help analysts determine if the software is malicious. You can choose to send some or all of the files in the list.
