A while ago I thought about what a perfect gateway Antivirus software would make to gain access to millions of machines. In order to stay up to date they are allowed to make regular calls home, are proprietary, and most often for end users even given away for free. Motivated by this post I just went through a list of the Worldwide Antivirus Vendor Market Share[1], looked up their country of origin, and I have to admit that I find the fragmentation of the industry and the internationalization quite remarkable. Of cause I have no datapoints for comparison, but I still find it interesting that so many nations are home to their very own Antivirus software provider.<p>Company Marketshare CountryOfOrigin<p>AVAST SOFTWARE 12.37% Czech Republic<p>AVG TECHNOLOGIES 12.37% Czech Republic<p>AVIRA GMBH 12.29% Germany<p>MICROSOFT CORP. 11.24% United States<p>ESET SOFTWARE 9.98% Slovakia<p>SYMANTEC CORP. 8.77% United States<p>KASPERSKY LABS 7.98% Russia<p>MCAFEE, INC. 4.50% United States<p>PANDA SECURITY 4.18% Spain<p>COMODO GROUP 2.79% United States<p>TREND MICRO, INC. 2.15% Japan<p>PC TOOLS SOFTWARE 2.00% Australia<p>EMSI SOFTWARE GMBH 1.16% Germany<p>SOFTWIN 1.11% Romania<p>F-SECURE CORP. 0.95% Finland<p>OTHERS 6.16%<p>[1] <a href="http://www.opswat.com/sites/default/files/OPSWAT-Market-Share-Report-June-2011.pdf" rel="nofollow">http://www.opswat.com/sites/default/files/OPSWAT-Market-Shar...</a>
