Online Virus Scan with Multiple Antivirus Software

Do you think you got a suspicious file? A scan with a single anti-virus software is sometimes not enough. Even installing multiple antivirus software isn't a great proposition, considering the fact that it will consume a good amount of your system resources. And then, there are chances of conflicts between different antivirus products.

If you still aren't sure after a successful scan, there are great alternatives available online. These sites can scan a single file with multiple anti-virus software. You only have to upload a file and it will be scanned by all of those antivirus softwares.
Lets take a look at some sites which offer these services for free.

Virustotal is a free online virus scanner that scans files with a whopping 32 antivirus engines. You saw it right! 32. It scans for viruses, trojans, worms and malware with :
Puff! That's one big list. Virustotal claims their virus definitions are updated real-time.
They also provide a small tool called VirusTotal uploader which adds 'Send to >> VirusTotal' in the Windows right-click context menu. With this tool, you can just right-click a file to upload for a scan. is similar to VirusTotal, except that it uses 18 virus scanners as compared to 32 used by the former.
The scanning engines include:
A-Squared, AntiVir, ArcaVir, Avast, AVG Antivirus, BitDefender, ClamAV, Dr.Web, F-Prot Antivirus, F-Secure Anti-Virus, Fortinet, Kaspersky Anti-Virus, NOD32, Norman Virus Control, Panda Antivirus, Rising Antivirus, VirusBuster, VBA32.

The virus definitions are updated hourly. They also have a limit of 10 MB on the size of files you can upload.

Off course with online scanners, there are the cons too. Scanning may take time as there are multiple engines involved. Sometimes you'll have to be in queue due to the heavy amount of processing that takes place. Also, this may not be the best choice for people who don't have a dedicated and fast internet connection.

And above all, a clean scan from any of these sites doesn't really mean a file is free of any virus or malware.
