VirusTotal, an invaluable free service to the Internet community, which utilizes 42 antivirus engines to analyzes suspicious files and URLs for all types of malware, recently released a Firefox only extension – VTzilla.
VTzilla is designed to scan URLs, links, and files (potential downloads) for malware, by employing the installed toolbar, or alternatively, the right click context menu.
Note: You can stop the toolbar from appearing, by making the required adjustment in Firefox’s: View – Toolbars.
Using the toolbar, I’ve plugged in my own site address as an example.
VirusTotal’s report indicates my site is a safe site, and does not contain malware.
Taking it one step further, (paranoid common sense), I’ve clicked on “View downloaded file analysis” within the report, which indicates all 42 engines found – there is no malware. The screen capture below, shows only part of the file analysis report.
The following two screen captures illustrated both my request to scan a link on my own site – Tighten Your PC’s Security With Free Encrypt Stick, using VTzilla’s right click context menu, and the “clean” result.
Next, I visited Download.com and set up a download. Before saving the file however, using the right click context menu again, I had VirusTotal perform a scan.
The result indicates a clean file.
A couple of caveats:
Regular VirusTotal users are aware that file size is restricted to 20 MB or less, and this restriction unfortunately, is still in effect for this new service.
VTzilla is available only as a direct download from the developer’s site at the moment. It should be available from Firefox’s add-on repository, in due course.
Overall, I think this extension has some value. But, it is not a panacea. More and more, if a site is imbedded with malware, just visiting the site can trigger a driveby download. Porn surfers particularly, need to take note of this.
System requirements: Firefox 1.5 – 3+
Download at: the developer’s site.

I was looking at this just yesterday. I am going to download it once it is available in Mozilla’s addon sections, I prefer to download my addons only from there. But it does look very good, VirusTotal is an excellent service.
I like the ability to check a download *before* downloading. The rest of the features though, I’ll wait and see.
This looks very interesting so I’ll add it to FF to see what it can do.
There’s no doubt that this addon has some value. How much value? I’ll wait and see.
Good to see you here.
I always use Virus Total to scan for files which I download from other users mainly on forums. It is a good website but the only thing it is missing is multiple file checking but I guess they will never introduce that feature since it will be abused also they have set a limit on file size which stops people from uploading huge file. It is unique and will check your file for viruses against 30-50 antivirus software definitions.
Wow, I just recently got a new laptop and I totally forgot to download back VirusTotal. Thanks for the reminder Bill, lol. Having a firefox add-on is definitely more convenient and useful. Thanks for all these great articles.
Another satisfied customer. 🙂
Glad you dropped by.
Hi Bill—thanks for your review of VTzilla. Do you know how much space it will take up in my computer? I don’t want to risk downloading anything that will slow it down. Also, I’ve been using Chrome lately, would you recommend any malware protection specifically for Chrome?
Well, since this is a cloud app it doesn’t really take up any space, in a real sense, on your machine. It does however, use a small amount of bandwidth while you’re connected to the net – as with all FF add-ons. The installer is tiny at 15.8KB.
Currently, I don’t use Chrome on a Windows machine, but I do use it on a Linux machine where I feel safe without any add-ons. If I remember correctly, when I ran Chrome under Windows, my *minimum *security config included NoScript, AdBlock Plus, and Better Privacy.
Good to see you visit. BTW, I was by your site just today http://blog.tune-up.com/ . Some great articles and advice.
Just a quick followup on your Chrome question.
A reader who’s an IT professional, and who’s judgement is of the highest order, uses the following Chrome extensions:
Chrome 6.0.472.41 (version numbers current at the time of writing)
AdBlock 2.0.24 DOES WHAT IT’S SUPPOSED TO DO AntiAds 0.4.0 AS ABOVE BitDefender QuickScan 0.9.9.34 HIGHLY RECOMMENDED – HIGHER VERSION THAN ON FIREFOX ChromeFlags 1.4 AS FLAGFOX FastestChrome – Browse Faster 3.1.2 IF FAST IS NOT ENOUGH FlashBlock 220.127.116.11 DIFFERENT VERSION NUMBER FROM FIREFOX Ghostery 2.0.0 DIFFERENT FROM THE FIREFOX VERSION, NOT YET PERFECT AND STILL EXPERIMENTAL Google Analytics Opt-out 0.9.0 ALTHOUGH I WOULD PREFER AN OPT-IN Google Dictionary 1.0.2 EVERYBODY NEEDS ONE Mini Google Maps 1.0.2 AS ABOVE Secbrowsing 1.7 UNDER EVALUATION SmoothScroll 0.6.1 UNDER EVALUATION Ultimate Google Docs Viewer 0.8.4.7 UNDER EVALUATION Wikipedia Companion 1.6.5 UNDER EVALUATION
Hope this helps.
