How to disable Windows Defender in Windows 10

Is turning off Windows Defender a good idea? We will find out very soon!


Windows Defender is the default antivirus application that comes with Windows 10. In the last two editions of the Microsoft operating system (Windows 8 and Windows 10) Defender bases its scanning engine on the Microsoft Security Essentials application (in fact disappeared and integrated into Defender) which certainly offers better protection against viruses and malware in general, also thanks to the constant updating of signatures via Windows Update and the fairly reactive real-time control.


Nevertheless third-party antiviruses offer even better protection, as we can see from our antivirus test.
