Windows Defender on Windows 10
Microsoft completely revamped Windows Defender in Windows 10. The tech giant added a series of important new features and improvements that make Windows Defender one of the best antivirus solutions to use in 2018. As a matter of fact, AV-Test, a reliable third-party testing company, recently placed Windows Defender on the first position when it comes to blocking real-life cyber threats, including ransomware attacks.
Here are some of the most important changes that Windows Defender received on Windows 10:
- Windows Security is the new antivirus center in Windows 10 Redstone 5

Windows Defender on Windows 8.1
Before Windows 8, Windows Defender featured antispyware capabilities. It included a number of real-time security agents that monitored several common areas of Windows for changes which may be caused by spyware. It also included the ability to easily remove installed ActiveX software. Also integrated support for Microsoft SpyNet that allows users to report to Microsoft what they consider to be spyware, and what applications and device drivers they allow to be installed on their system. In Windows 8, functionality has increased to offer antivirus protection as well. Windows Defender in Windows 8 resembles Microsoft Security Essentials and uses the same virus definitions.
So, as we can see from the above description, along with the release of Windows 8, the Windows Defender utility has been made much stronger and similar to how Microsoft Security Essentials works. You can configure the program for real-time protection options, Internet Explorer integration and, of course, to scan files on your system whenever you want. At the moment, Windows Defender only works in desktop mode, and it’s unlikely, at least for now, that it will be released for the modern, touch interface of Windows 8.1.
