Microso�’s Security Essentials Antivirus leads the North American Market for individual products with 10% market share, a 2.5% increase since our September 2010 report.“Free” antivirus solutions also accounted for 3 of the top 4 antivirus products detected globally, as avast! Free Antivirus, Microso� Security Essentials, and AVG Anti-Virus Free were all available as free downloads.

ConclusionIn North America, fi�y-three different antivirus companies were detected in this report. Of those fi�y-three, five companies combined to control 60.74% of the antivirus market. While Symantec still controls a large part of the market, trends are moving away from paid antivirus so�ware and towards free antivirus solutions such as those from Microso�, AVG, and AVAST So�ware. Our current data shows that 58% of respondents were using a free solution, confirming our trend noted above when compared to a 42% free solution share as shown in our June 2010 report.When looking at worldwide data, the top three vendors are AVAST, ESET, and Symantec, together controlling nearly 40% of the market. The same three vendors also control more than 40% of the North American market, with Symantec leading the way with 16.45% market share. Of the ninety thousand reports that were submi�ed worldwide, only 60% of those reports detected having any antivirus application installed.

Backup Clients are becoming more and more popular as the importance of securing data increases. A�er analyzing worldwide backup client usage data, we were able to detect that nearly 47.83% of users with an installed backup client, backed up their data within one day. Of those we could detect, there were 26.09% of users who backed up their data between 1 day and 1 week. This data shows us that almost 75% of all users with backup clients are using them weekly, with nearly 82% of all users backing up their data at least monthly. This data was taken from a sample of reports received that used backup clients by Carbonite, Panda, Bullguard, Soonr, Avanquest and Mozy.

Backup Client Adoption

Of the top 17 backup client vendors OPSWAT was able to detect globally, Norton claimed the most market share with 26.49%. Rounding out the top 3 in backup client market share are McAfee 10.58% and Dropbox 10.41%.

Backup Client Market Share

ConclusionCompanies that offer all-inclusive security packages which include backup clients, such as Norton and McAfee, are at the top of the charts when it comes to market share. Their bundled, as well as standalone backup clients, help them control the backup client market. The most prominent example of a standalone backup client is Dropbox, who holds the third largest market share at 10.37%. This shows that standalone backup clients can still compete with all-inclusive security suites.
