VirusTotal is a service that analyzes suspicious files and now URLs and facilitates the quick detection of viruses, worms, trojans, and all kinds of malware detected by antivirus engines. It thus enables the identification of viruses, worms, trojans and other kinds of malicious content detected by multiple antivirus engines and web analysis toolbars.
Earlier it only scanned suspicious files, by uploading them to their server and checking them with definitions of several antivirus software.
VirusTotal URL scanner
The new VirusTotal URL scanner uses several services like those of Firefox, Google SafeBrowsing, Opera-AVG, Phishtank, Internet Explorer’s SmartScreen filter and TRUSTe.
VirusTotal Browser extension
VirusTotal has also now made a browser extension for Internet Explorer, Firefox, and Chrome.
VTexplorer for Internet Explorer, VTchromizer for Chrome and VTzilla for Firefox are browser plugins that simplify the process of scanning Internet resources with VirusTotal.
They allow you to download files directly with VirusTotal’s web application before storing them in your Windows PC. Moreover, they will scan not only files, but also URLs.
The scanning options are embedded in the context menu and download dialog, making the analysis process as easy as clicking a single button.
