VTzilla: Scan Unknown Emails, Suspicious Websites & File Downloads In Firefox

VTzilla is an add-on for Firefox that makes it super simple to scan the Internet with VirusTotal. The add-on not only lets users scan suspicious files and emails before downloading them, but even supports URLs. What’s more, you will find the option to scan a particular file embedded in the context menu of Firefox, making the entire virus scanning process all the more easier.

When you have installed the add-on, you will see the VirusTotal toolbar appear in Firefox. It will also be accessible from the context-menu of Firefox.



There are many different ways in which you can use this application to keep your PC safe from viruses and other threats. One option is to scan all emails received from unknown senders with this tool before opening them. Another option is to right-click on any link to make sure it can safely be opened and does not have any viruses. Yet another method is to scan an entire website, especially if you’re visiting it for the first time, by entering its URL into the Search VirusTotal box in toolbar. Whenever you download a file after installing this add-on, you will be prompted to scan the file with VirusTotal before proceeding with the download. This is an extra precautionary measure taken to protect your PC.


The developer intends to develop a safer online community. Any site that is checked for viruses is added to VirusTotal database. Users can also leave behind their reviews on what they think about the site. In case, someone had a bad online experience, he can share it with others by entering his comments into the site’s review. Anyone using this tool to scan the same website in future will come across the comments and hopefully get help from the reviews you leave.
