With more than 25% of the worldwide market, Microsoft ranks with the highest share of any antivirus vendor in this report, followed closely behind by Avast at 23.6%. The remaining competitors, each with a market share in the single digits, are led by AVG and Symantec at 9.1% and 8.4%. According to the data, the top ten antivirus vendors control more than 93% of the market. Only antivirus products with real time protection (RTP) enabled are included in this comparison. A product with RTP enabled is currently running on a user’s machine, while a product without RTP enabled is expired or disabled.

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. When RTP status is not a factor, Microsoft’s market share increases dramatically, accounting for about a third of all antivirus installations, while Avast trails at 19.1%. The remaining products all show a reduced share due to Microsoft’s increase in the number of data points. This change in ranking indicates that more Microsoft antivirus products are likely to be disabled, in comparison to the products of other top antivirus vendors. In the section below that covers antivirus products, this discrepancy is attributed to Windows Defender’s low rate of RTP activation.
In the worldwide market of antivirus products with real time protection (RTP) enabled, avast! Free Antivirus ranks as the leader, with a share of 19.7%. Microsoft Security Essentials follows closely behind at 18%. These two leaders are far ahead of the remaining products on the list, which are led by Windows Defender and AVG Antivirus Free Edition at 7.6% and 5.8%. The top ten products make up 74% of the worldwide antivirus products that were detected. A product with RTP enabled is currently running on 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.
|Antivirus Product||Market Share|
|A||avast! Free Antivirus||19.5%|
|B||Microsoft Security Essentials||18.3%|
|D||AVG Anti-Virus Free Edition||6.1%|
|E||Avira Free Antivirus||5.5%|
|F||Norton Internet Security||4.1%|
|G||ESET Smart Security||4.1%|
|H||Kaspersky Internet Security||3.2%|
|I||AVG Internet SEcurity||3.1%|
|J||avast! Internet Security||2.8%|
|K||ESET NOD32 Antivirus||2.5%|
The ranking of all installed antivirus products, regardless of whether real time protection (RTP) is enabled, tells a different story. In this expanded set of data, which includes expired and disabled products, Windows Defender tops the list with more than 19% of the market, with little change among the remaining products compared to the previous data set. This dramatic jump from a distant third to a comfortable lead indicates that Windows Defender has a very low rate of activation compared to other top antivirus products. Windows Defender is pre-installed on all computers that contain Windows 8. A high proportion of Windows 8 users in this data set have opted to disable Windows Defender and, in most cases, have installed other antivirus products that are actively scanning their machines. Furthermore, this data set contains a higher percentage (22.3%) of Windows 8 users than is found by other sources. For example, NetMarketShare found Windows 8 users to make up about 5.8% of the Windows market.
After further filtering, the antivirus product data shows that about 65% of Windows 8 users have an additional antivirus product (with real time protection enabled) on their machines. Security Essentials, Microsoft’s second product at the top of the list, shows much different characteristics. Most users who have Security Essentials installed do not have an additional antivirus product installed that has RTP enabled. This comparison is illustrated in the pie charts below.
RTP status can be seen as a metric for product usability and/or effectiveness; if a user views an antivirus product as effective and easy to operate, the user is more likely to have that product actively running on his or her machine. In the set of data used in this report, nearly all products have RTP enabled at a rate of at least 80%. The exception is Windows Defender, which has a much lower rate of around 30%. As explained in the earlier in this section, this product is natively installed with Windows 8, and the majority of these users are actively using a different antivirus product. On the other end of the spectrum, Microsoft’s other antivirus product, Security Essentials, has the highest rate of RTP being enabled, at 98%, followed closely by Avira Free Antivirus at 97.4%. McAfee VirusScan (95.6%) and Norton Internet Security (94.9%) also rank high on the list.
In a comparison of public file sharing, or peer-to-peer (P2P), products, µTorrent dominates, with more than 50% of the market. BitTorrent, which is owned by the same company, follows at 7.4%. Ares, Free Download Manager, and Vuze lead the remaining products, each with between four to six percent of the market. Though the overall data includes many other detected products, the top ten P2P products make up of 91.5% of the market. Products are included in this section regardless of whether or not they are running.
|P2P Product||Market Share|
|D||Free Download Manager||5.2%|
The market for backup products is much more evenly distributed when compared to the public file sharing application market. Google Drive leads the the ranking with 22.3%, followed by Dropbox, SkyDrive, and iCloud, each in the double digits. The top ten products make up 83.3% of the market, which means that several competitors that did not make the list make up a significant portion of the backup product market. Both Windows Backup & Restore and Windows File History have been removed from the data set since they are built into computers running on certain Windows operating systems.
|Backup Product||Market Share|
|E||Acronis True Image||4.6%|
|G||Norton Online Backup||2.8%|
|I||Paragon Backup & Restore||2.1%|
For the first time, this report includes data related to antiphishing products. Out of all users in the data set, 92.1% have antiphishing enabled in at least one of their browsers.
This report shows comparisons for antivirus, peer-to-peer, backup, and antiphishing applications on Windows systems from data collected from users of OPSWAT’s Security Score tool, a free product that utilizes the detection capabilities of OPSWAT GEARS to collect information regarding the applications installed on endpoint computers. Security Score is available at opswat.com/products/security-score and also at various download sites across the web. This tool is used around the world by home and business users, both expert and inexperienced in security software. For the purpose of the report, the sample of more than 3000 users is assumed to be representative of the market, based on the wide accessibility of the tool to a large range of users. However, these results are likely to differ from those in the real world (see below for more details).
This is the first market share report that exclusively uses Security Score data, as opposed to past reports that used data from AppRemover. For the purposes of the report, data collection from Security Score is expected to be an improvement over data compared to AppRemover for the following reasons:
However, several attributes inherent in way the data is collected may cause the results in this report to differ from what exists in the real world. OPSWAT makes no claims as to the accuracy of the data in the real world market and is continuously working on ways to overcome the following obstacles:
Stay tuned for the next market share report in October, which will feature new comparisons and in-depth comparisons of product usage. OPSWAT is working to increase global usage of Security Score and other free applications. Mac application data will also be added in the future.
Vendors of antivirus, P2P, backup, and other applications interested in inclusion in these reports and GEARS Cloud are encouraged to contact email@example.com to learn how to partner with OPSWAT.
