Windows Defender (WD) is free software built into the Windows operating system, which is useful for protecting your device from viruses, malware, ransomware, spyware, etc.

But recently, around the time Windows 8 was released, Microsoft turned Windows Defender into a free anti-virus which is quite good at providing system security.

For example, with cloud-based sandboxing and malware detection features, Windows Defender can detect threats quickly and improve overall protection.

Despite all the improvements and security features of the system, it turns out that many Windows users still don’t like the existence of Windows Defender.

The reasons are quite varied. Starting from weighing down the performance of your PC or laptop, to having to use another, better anti-virus.

But what is more often encountered is that Windows Defender likes to ‘at will’ block applications that are about to be installed. Even though the application is an official and licensed application.
