Firefox Only: Easily scan files for malware before downloading them with VTzilla

We have all heard of VirusTotal [1], right? (You know, VirusTotal.com, the website that allows users to run files through 43 anti-malware scanners.) VirusTotal is a very handy service, but in order to use VT (VirusTotal) you need to download a file, then upload it on VT. Ever wish you were able to scan a file with VT before you download it?

To try to get users to make use of their new URL scanner, VirusTotal has programmed VTzilla in such a way that when scanning a file, users are first displayed the results of the URL scanner and then have the option to view the results of the file scanner. (Unfortunately there is no way to change this behavior. I hope an option is added in future updates allowing users to view the results of the file scanner first.) To access the file scanner results from the URL scanner results page, click on View downloaded file analysis found on the URL scanner results page:


Other things worth noting regarding VTzilla:



This toolbar allows users to 1) Scan the current website you are surfing [via the URL scanner] 2) Search VirusTotal database/community. However, personally, I find this toolbar to be more annoying than useful. Fortunately, you can turn it off easily by going to “View” -> “Toolbars” and unchecking “VirusTotal Toolbar”. (You may also right-click on the toolbar and uncheck “VirusTotal Toolbar”.)

That said, you can download VTzilla from the following links:
