"VirusTotal and confidentiality
Files and URLs sent to VirusTotal will be shared with antivirus vendors and security companies so as to help them in improving their services and products. We do this because we believe it will eventually lead to a safer Internet and better end-user protection.
By default any file/URL submitted to VirusTotal which is detected by at least one scanner is freely sent to all those scanners that do not detect the resource. Additionally, all files and URLs enter a private store that may be accessed by premium (mainly security/antimalware companies/organizations) VirusTotal users so as to improve their security products and services.
