Microsoft Windows Defender


The antivirus made by Windows, for Windows


  • Comprehensive antivirus developed by Microsoft.
  • Protection in the cloud and real time.
  • Constant automatic updates.


  • It deactivates if you install another antivirus.

Microsoft Windows Defender is a piece of software that shields your computer against pop-ups, slow running speeds, and security threats caused by malware. It tracks down spy software that causes slow running speeds and that uses your private information without your consent.

A comprehensive tool

Microsoft Windows Defender allows for on demand or scheduled scans, through which it’s possible to examine your computer in great depth. It works quietly in the background, protecting Windows from all types of threats, while you get on with your work. It has infinite benefits, especially considering that it constantly keeps itself up to speed with the latest threats by updating regularly.

Microsoft Windows Defender also includes tools to detect the most modern types of malware, such as the detection of threats in real time and cloud protection. These two things are designed to detect malware way before it gets a chance to cause any damage, as they constantly revise the behaviour of installed programs; if anything starts to behave strangely, the alarm bells will start ringing and Microsoft Windows Defender will know it needs to investigate the anomaly.

Windows through and through

Originally, Microsoft Windows Defender was called Microsoft Antispyware. The idea of the program was to fight against spyware (obviously), but the proliferation and complexity of current threats meant that the program needed a new focus. In the latest versions of Windows, Defender comes installed as default but is sometimes deactivated by other antivirus programs that are installed on the PC. This is due to the fact that, in general, two antivirus programs working at the same time can cause problems.

For this reason you can configure this software to be the default option and browse the internet without fear that hackers will get access to your personal details. All you need to do is indicate that you want it to be your default option (although you may have to deactivate other antivirus programs, too).

It’s light on memory, it updates all the time, and you won’t even notice it’s working. Could it be any more comprehensive? Install Microsoft Windows Defender and discover for yourself!
