VirusTotal has released version 2.0 of their VTZilla Firefox extension so that it now supports Mozilla Quantum and includes additional features. With this release of VTZilla, VirusTotal added new features such as the ability to scan downloaded files automatically, scan links or pages, or enter a hash to pull up an existing report.
According to VirusTotal, due to the changes in how Firefox extensions need to be developed, they decided to redesign VTZilla with certain goals in mind.
Automatically scanning downloaded files
When this extension is installed and you download a file, VTZilla will automatically submit downloaded files for scanning on VirusTotal. When done, it will display links to two different scan reports.
The VirusTotal URL report is a report on the URL and the File report is a scan of the actual file that was downloaded. For the most part, the File report will be most useful for users.
By using this feature you can make sure that any downloaded files are safe before you execute them.
