What Is VirusTotal?

VirusTotal is a complimentary service that analyzes files and URLs for viruses, worms, trojans, and other types of malware. Their goal is to make the internet a safer place through collaboration between members of the antivirus industry, researchers, and end users of all kinds. 

How It Works

VirusTotal inspects items with over 70 antivirus scanners and URL/domain blacklisting services, in addition to a myriad of tools to extract signals from the studied content. Any user can select a file from their computer using their browser and send it to VirusTotal. They offer a number of file submission methods, including the primary public web interface, desktop uploaders, browser extensions, and a programmatic API.

As with files, URLs can be submitted via several different means including the VirusTotal webpage, browser extensions and the API.

Upon submitting a file or URL basic results are shared with the submitter, and also between the examining partners, who use results to improve their own systems. As a result, by submitting files, URLs, domains, etc. to VirusTotal you are contributing to raise the global IT security level.

This core analysis is also the basis for several other features, including the VirusTotal Community: a network that allows users to comment on files and URLs and share notes with each other. This tool can be useful in detecting malicious content and also in identifying false positives — normal and harmless items detected as malicious by one or more scanners.

Detailed Results

VirusTotal not only tells you whether a given antivirus solution detected a submitted file as malicious but also displays each engine’s detection label (e.g., I-Worm.Allaple.gen). The same is true for URL scanners, most of which will discriminate between malware sites, phishing sites, suspicious sites, etc. Some engines will provide additional information, stating explicitly whether a given URL belongs to a particular botnet, which brand is targeted by a given phishing site, and so on.
