Free Microsoft Security Essentials Is Most Used Antivirus Worldwide

By on June 11th, 2011 09:00 GMT

Microsoft Security Essentials is the most popular security solution worldwide according to a report by OPSWAT covering the second quarter of 2011, March 23 to May 15, 2011.

Microsoft’s free antivirus offered to users of genuine Windows operating systems including Windows 7 RTM and SP1, has been found to run on no less than 10.66% of the 43,000 computers around the world covered by the OPSWAT’s Q2 Antivirus Market Share Report.

Microsoft Security Essentials, now at version 2.0 which was released at the end of 2010, is a free, basic security solution that the software giant launched initially in 2009. The Redmond company’s only statistics about MSE made public reveal that the AV has long passed the 30 million downloads mark.

According to OPSWAT, the free version of Avira Antivir Personal comes in second place as most used antivirus worldwide with a share of 10.18%, while AVAST! Free Antivirus is third with 8.66%.

When it comes down to Worldwide Antivirus Vendor Market Share, things are a tad different however. Since AV vendors have more security offerings than Microsoft, they also have a larger market share.

“AVAST Software and AVG Technologies both top this quarter’s worldwide antivirus market with 12.37% each. AVAST shows a decrease from its leading 16.19% last quarter, which could be due to a shift in the percentage of data originating from various countries. Avira and Microsoft rank third and fourth with 12.29% and 11.24% of the market, respectively,” OPSWAT notes.

“Microsoft’s gain from last quarter could be attributed to the distribution advantage that Microsoft Security Essentials holds due to the convenient installation through Windows Update and its smooth integration with the popular IE browser.”

At the same time, OPSWAT’s report indicates that Microsoft is king on the North America market with a share of no less than 17.07%. AVG is runner up with 15.63%, followed by Symantec with 14.47%.

Once again, OPSWAT stresses that responsible for the market share growth of Microsoft Security Essentials is the Redmond company’s move to push the security solution through Windows Update.
