Worldwide Antivirus Vendor Market Share
As seen in past reports, Microsoft leads worldwide antivirus vendors with more than a quarter of the market, and Avast follows closely behind with 23.6%. The remaining antivirus vendors all show market shares in the single digits, with AVG, Symantec, and ESET leading this tier. The top ten antivirus vendors control 92% of the market. Only antivirus products with real time protection (RTP) enabled are included in this comparison. A product with RTP enabled is currently actively protecting a user’s machine, while a product without RTP enabled is expired or disabled. In the table to the right, clicking each vendor name will reveal the distribution of component products within it.
While the comparison above only includes data from products with real time protection (RTP) enabled, OPSWAT also looked at data for all installed products, including those that are expired or disabled. If RTP is not enabled, the product is installed on the user’s machine but not actively protecting it. When RTP status is not a factor, Microsoft’s lead in market share increases by 8%, while Avast’s share decreases by 5%. Similarly, all the other top vendors show decreased market share in this comparison. This result reveals that a high number of users who have Microsoft antivirus products installed on their machines do not have these products running. The next section, which shows comparisons by product, gives more insight into the difference in RTP status between Microsoft’s products.
Worldwide Antivirus Product Market Share
In the worldwide market of antivirus products with real time protection (RTP) enabled, avast! Free Antivirus ranks as the leader, with a share of 19.6%. Microsoft claims the next two positions, with Security Essentials and Windows Defender at 17.2% and 7.8%. The other products that showed more than four percent of the market include Avira Free Antivirus, AVG Anti-Virus Free Edition, and ESET Smart Security. The top ten products control 72.1% of the market. A product with RTP enabled is actively protecting a user’s machine, as opposed to products that are expired or disabled. Only these active antivirus products are included in this section of the report.
The ranking of all installed antivirus products, regardless of whether real time protection (RTP) is enabled, shows one big difference from the graph above. In this expanded set of data, which includes expired and disabled products, Windows Defender tops the list with almost 20% of the market. This is more than double the product’s market share when only products with RTP enabled are compared. This huge adjustment caused by Windows Defender in this data set causes every other top antivirus product to lose market share in the comparison. Besides the change in Windows Defender, the ranking of products is the same as that seen in the RTP enabled comparison. One noteworthy conclusion drawn from this data set is that Windows Defender is much more likely to be disabled on a person’s computer compared to other top antivirus products.
Worldwide Antivirus Product Comparisons
This graph shows a comparison between desktop and laptop users within each top antivirus, and considerable differences are seen across products. The only product with noticeably more users on laptops, as opposed to desktops, is McAfee VirusScan, with a 65/35% ratio. Windows Defender leans very slightly toward desktop users, but all other top antivirus products show significantly more desktop users. The products with the highest percentage of desktop users are Kaspersky Internet Security, with 66.3%, followed by Norton Internet Security at 62.8%. These results only include products with real time protection enabled.
This section features a cross comparison between windows operating systems and the top antivirus products found on them. Only the top six products, and only those with real time protection enabled are included in this comparison. Windows Defender is by far the most common antivirus product found on Windows 8 operating systems. Microsoft Security Essentials is evenly represented across Windows XP and Windows 7, and avast! Free Antivirus is most commonly found on computers with Windows 7. If only Windows XP users are considered, Avira Free Antivirus becomes the second-ranked antivirus product, and ESET Smart Security follows. These results only include products with real time protection enabled.
In the previous comparison, computers with Windows Defender installed were the most likely to have another antivirus product installed. Windows Defender, as an antivirus product, is only available on Windows 8, where it is pre-installed, integrated in the operating system, and impossible to remove without hacking the system. The result is that Windows 8 users, at almost 65%, are much more likely to have another antivirus product installed than are users of other operating systems, which are each around 20% or lower. Windows XP is lowest at around 9%. This comparison includes all products, whether or not they have real time protection enabled.
