OPSWAT Report on Worldwide Antivirus Application Market Share

On July 7, OPSWAT, Inc. published a report on “Worldwide Antivirus Application Market Share”. The results may not mesh completely with the results published by the vendors themselves (surprise!). The study period was January through May 2010. Note that these are antivirus deployments, not internet security suite deployments.

By product, the top 5 Windows antivirus deployments over the study period, by product were from los Free Amigos (Avast!, Avira, and AVG Technologies) and Microsoft.

• avast! Free Antivirus 11.45%
• Avira AntiVir Personal - Free Antivirus 9.19%
• AVG Anti-Virus Free 8.6%
• Microsoft Security Essentials 7.48%
• avast! Antivirus 5.4%

The order of the top 3 may be surprising to some people since on CNET’s sight the typical weekly download order for the top three is AVG, followed by Avira and Avast. isn’t the only download site for these vendors.

The top 5 Windows antivirus market share leaders by vendor for the same period were

• AVAST Software 19.14%
• Avira GmbH 11.39%
• Symantec Corp. 10.06%
• Microsoft Corp. 9.29%
• AVG Technologies 9%

A more comprehensive listing can be viewed on the links below.

The vendor share reflects both paid and free AV, business and consumer. So the Symantec data includes both the Norton and Symantec AV brands. It does not include PC Tools, which they own. AVG Technologies drop in ranking from the product deployment table to the vendor deployment table relative to that of Avast! And Avira may signify that a much higher proportion of AVG’s installed base is their free software compared to the other two companies.

European vendors comprised 52% of the deployments, and North America 31%.
