What I've tried:
- VirusTotal by VIRUSTOTAL - Only scans installed apps
- VirusTotal Mobile by Funnycat - Cannot rescan using current definitions
- VirusTotal Uplink by Frizzware - Cannot rescan using current definitions
Not tried, but according to reviews, will not meet requirements:
- VirusTotal Uploader by Vitaly Novitsky - According to reviews, cannot rescan using current definitions
I am open to recommendations that use any service that scans using multiple antivirus/malware engines (using VirusTotal is definitely not a requirement).
