Type Free online antivirus file scanning
License Free online service

VirusTotal is an online service providing free malware scanning for individual files. It is not software installed on the user's computer, so it does not perform system-wide malware scans. The service performs aggregate tests using over 40 different antivirus products.[1] Tests can be run either on the website or through e-mail.[2] The variety of antivirus software used by the website allows a user to check for malware that his/her own antivirus solution may have missed, or to verify false positives.

VirusTotal was selected by PC World as one of the best 100 products of 2007.[3]

  • Since VirusTotal is a public service, malicious programmers can submit samples of their work to VirusTotal for analysis, and determine how to bypass detection methods of new threats through trial and error.[4]
  • VirusTotal is limited in that it can only scan files up to 20 megabytes in size submitted via its web interface or its e-mail interface.
  • Due to the nature of the service, files must be scanned on-demand, causing a backlog to build up at peak times. The website displays detailed graphs of server traffic, and archives these.
  • The antivirus programs used by VirusTotal have limited disassembling power, and VirusTotal does not execute the files for more comprehensive analyses.
  • Antiviruses used may not provide 100% accurate results.


  • VirusTotal has created its own uploader, which enables users to directly send files from their system using the context menu, to scan for virus.
