VirusTotal

VirusTotal is a service that analyzes suspicious files and facilitates real-time detection of viruses, worms, trojans and malware content.

VirusTotal, a subsidiary of Google, is a free online service that analyzes files and URLs enabling the identification of viruses, worms, trojans and other kinds of malicious content detected by antivirus engines and website scanners. At the same time, it may be used as a means to detect false positives, i.e. innocuous resources detected as malicious by one or more scanners.
