Quote:Virustotal, an online virus scanning service operated by Google, is a handy resource to verify that files are clean before you execute them on your devices.

All it takes is to visit the Virustotal website, drop a file on the interface from the local system, and wait for the scan results to be displayed after the scan.

The service is ideal to get a quick overview of a file's reputation. Results are not 100% trustworthy especially if some engines report hits while others don't; the likelihood of false positives is higher on Virustotal than with any one antivirus engine that you check files against.

Virustotal maintains an email scanning service next to the Web version and the APIs that it provides. You send emails with a file attachment to the service and get a report soon thereafter as a reply.
