VirusTotal is an online virus scanner for malware analysis by Google. It is widely used around the world to analyze suspicious files and URLs. VirusTotal uses a simple concept of scanning a suspicious file or URL using more than 50 malware scanners. If you regularly download from the Internet, your regular antivirus installed on your computer or Mac, is not enough to offer you 100% security. To be 100% sure that the file you just downloaded is free of any malware, a second opinion is always welcomed. That’s where online malware scanners like VirusTotal fit themselves. It’s not a replacement for your antivirus software as it is not installed and neither have any real-time scanner. Once you upload a suspicious file for scanning using the web interface, VirusTotal uses more than 50 scanners to analyze the file and tell you if the suspicious file is infected with any virus, worm, trojan, or any other kind of malware. For some Mac users, using the online web interface of the service to upload files for scanning is not very convenient. For them, the service has released a new desktop tool called VirusTotal Uploader for OS X.
