If Security Essentials 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 to send a sample, Security Essentials 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.
