Windows Defender developed by Microsoft since Windows 10 has become the default security software pre-installed on this operating system. In fact, this pre-installation method of Microsoft has also caused complaints from developers such as Kaspersky, because this way will seize the market share of other security software. The improved way of Microsoft is that if the user does not actively install other anti-virus software, Windows Defender is enabled as the defense software by default. If the user has installed other anti-virus software, Windows Defender will automatically shut down, unless the user uninstalls other anti-virus software, it will not be enabled by default.
The Microsoft security team said that Windows Defender has become the industry’s leading anti-virus solution and its market share is growing. According to Microsoft telemetry data, Windows Defender anti-virus software has more than 500 million monthly active users, and more and more users use the security software. In terms of market share, the market share of Windows Defender anti-virus software in the Windows operating system has exceeded 50%. This means that the combined market share of other anti-virus software is only 50%, which is obviously not optimistic for other anti-virus software developers.
With such a high market share and so many users, Windows Defender anti-virus software itself has become the main target of hacking. Because hackers can successfully discover Windows Defender’s vulnerability and successfully exploit it, it will be able to launch an extremely wide range of attacks around the world. In fact, Microsoft is more worried about this issue. Microsoft said that Windows Defender has become a big target to attract attackers to launch attacks. Because attackers want to break through Windows Defender to get the most victims, which in turn makes Microsoft pay more attention to the security of the software itself.
