Windows Defender is the built-in antivirus in your Windows 8 and Windows 8.1 device and it’s quite good, at least for me. The purpose of this article is to keep an easier to understand changelog of the latest updates that have been made available.

If you don’t feel like you want to install another antivirus program on your Windows 8.1 device, then you can rely on Windows Defender as it seems to be performing its job quite well. However, if you have decided to stick with it, then make sure you get the latest updates, as soon as possible. Of course, the easiest way to do that is to set to receive updates automatically, but if you’re curious to learn what they are about, you will want to set that to manually. And here, we are going to review the updates as often as we can an provide an easier to understand changelog.

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.
