Virus Total Scanner analyzes suspicious files with more than 40 well-known antivirus engines, using the VirusTotal web service.
Select the file and then click on Virus Total Scan. The app checks the MD5 hash of the file and checks if you have already scanned it. If you have, it'll show you the relevant report.
However, if the file has never been analyzed before, you'll be required to upload it manually on the VirusTotal site. Virus Total Scanner, unfortunately, can't do this automatically.
