VTzilla is a Mozilla Firefox browser plugin that simplifies the process of scanning Internet resources with VirusTotal. It allows you to download files directly with VirusTotal’s web application prior to storing them in your PC. Moreover, it will not only scan files, but also URLs.
The scanning options are embedded in Firefox’s context menu and download dialog, making the analysis process as easy as clicking a single button.
VTchromizer is a Google Chrome browser extension that simplifies the process of scanning Internet resources with VirusTotal. It allows you to scan links (including links to files) directly with VirusTotal’s web application. It will scan the submitted URLs with URL analysis tools and the content downloaded from the scanned site with VirusTotal’s antvirus solutions.
Unlike VTzilla, VTchromizer does not embed itself in the browser’s download dialog, only in the context menu. Google Chrome still does not offer an API to modify the download dialog, having said this, you can still scan any file that you want to download by right-clicking on the link to the file and choosing the Scan with VirusTotal option.
