No surprises then, that these services are not very popular these days. Their number has dropped from over 60 to around 5. Those services were useful for quick scans and getting second opinion, as they did not interfere with the antivirus you had installed on your system. But most of these online antivirus scanners did not have the ability to remove or clean any malware they found — they were mere detection tools.
You can now use web based multiengine antivirus scanners, which are basically online services that allow anyone to upload files and have them scanned with a number of different antivirus programs, including the majority of the most popular ones like Avast, Bitdefender, Kaspersky, Malware, Panda, and Symantec. There are a handful of such services now available, with the most popular being VirusTotal. It scans the files you upload with over 70 scanners, confirming whether it contains any malware like virus, Trojans, worms, and more.
VirusTotal is one of the foremost multiengine online virus scanners around. It launched all the way back in , but was acquired by Google in This means that it has access to the best infrastructure, when compared to its competitors, and the most antivirus engines. This is a very feature rich service, and can not only scan your files, but also comes with URL scanning, additional information on the analyzed files, support for multiple languages, as well as voting and comments.
If anything, the community aspects of VirusTotal are second to none. In terms of its UI, VirusTotal is the cleanest of the bunch.
It puts up a handy safe-o-meter that lets you gauge at a glance whether your chosen file is safe or not. And you can also click on the tabs to view detailed information about the product or company, version numbers, even original file name. And not only can you scan files, VirusTotal can also check if a website is safe to visit — very much similar to a good browser or internet security suite that come with browser addon. You can scan and analyze URLs to double check whether you should proceed to visit, or avoid suspicious sites altogether.
VirusTotal is simple enough to use. Either drag the file that you wish to scan into the selection box on the VirusTotal website , or click on the Choose File button and navigate to it. Once the upload is complete, the service will begin scanning the file using all the scanning engines it has at its disposal. After the scans are completed, you are presented with a summary page that contains the results of all the individual scans.
You can use VirusTotal to not just scan program installers, executables and firmware files, but the service can be used to detect malware in any file — from Word documents and PDFs to images, sounds and videos.
For common files, you will probably see a popup that notifies you that your file has already been analyzed recently. You can either view the analysis, or if the date was months ago, reanalyze it. If your file gets a clean bill of health from these scans, there is a fair chance that it does not come packing malware.
In case of a false positive, you can also perform a web search on the file name and often find people discussing whether it is a virus or not. That is all fine and dandy. But how to use the service to scan the files you want to download before you download them?
Glad you asked, because not only are there multiple ways to send files to VirusTotal, there are also a couple different ways you can make sure what you are downloading is safe. The service takes files from web, email, browser extensions, desktop programs and mobile apps, and even comes with a free public API. This means you can scan remote files just as easily as you can do so local ones. Simply go to the URL tab, and enter a direct link to the file you want to download and scan.
You can then download the file analysis that the service prepares for you. And for those of you who regularly deal with downloads, you can also integrate VirusTotal into your browser. The service offers browser extensions that allow you to right-click a link on any webpage and start scanning without visiting the VirusTotal website and copying and pasting the link there. Locate the file that you have downloaded, right-click it and you should see an option to scan it with the security software you have installed on your system.

Consider who you are downloading the file from. Think about it logically, if you're downloading something from Microsoft, it's not likely that you're downloading a virus. What's the context? That's the key. Are there other people that have downloaded the file? If there's a forum attached to the site that has people saying they've downloaded said file and have not experienced any problems, chances are, you aren't going to be downloading a Trojan or worm.
Look at the size of the file. If it's too small for what it is, it's junk. Watch out for executable files, such as '. If you download one of these you are, potentially, opening yourself up to anything on that file once you activate it. Try scanning it with a virus checker or any other software that is like it - just to be on the safe side.
One common trick used by crackers is to have a 'double extension' such as '. Said file is actually an. Is the file signed? If you are downloading an executable. If the executable is unlicensed, it is most likely a threat to your computer and privacy. Note that not all unlicensed executables are bad, nor are all licensed executables good.
