Antivirus - Check files/Website/email in real time on all Antivirus vendors

During these years I often had necessity to check files/emails/Url to understand if they had any sort of infection that was not yet discovered from latter antivirus definitions.

To get this result often I connect through this website that query all major AV versions and relative latter definitions.

Decisively useful.
