How To Turn Off Windows Defender In Windows 10 Permanently

The Windows Defender is built-in antivirus software that was designed to protect your system from all kinds of threats or viruses that have intentions of stealing your information, infiltrating your privacy, deleting or corrupting important files, and rendering your computer useless or putting it in a vegetative state.

Being one of the best available antivirus programs, it notifies you about the activities that may risk your system to ransomware, spyware, rootkits, trojans, and other forms of malicious attacks.

Sometimes you will be pushed to a spot where you have to disable Windows Defender to get work done. This article will tell you how to turn off Windows Defender in Windows 10 computers.

Reasons to disable the Windows Defender Antivirus on your Windows 10 computer

Although Windows Defender is a great alternative for any antivirus program, it can easily frustrate users by restricting them from performing certain tasks. 

There are two main reasons that can force you to turn off Windows Defender on your Windows 10 PC:

Reason 1: The Microsoft Defender antivirus is preventing you from downloading or running certain programs

If you are trying to install certain third-party software or programs, the Windows Defender will not allow you to do so since it is programmed to treat every third-party program as a threat.

Even if the software you wish to install onto your system is safe and is also from a legitimate developer and a credible source, the Windows Defender will continue to delete the software from the system without you knowing that this has been taking place.

Eventually, you will be able to notice that this application or feature is missing only when you wish to use it and thereby look for it. 

Reason 2: The Microsoft Defender antivirus is using up a lot of resources

The Windows Defender may consume a lot of resources and over-occupy the processor while scanning files on your system. It might further affect your system’s performance if you are using a system with lower RAM. Hence, you must ensure that Windows Defender is turned off to take proper control over your system. 

Can I Disable the Windows Defender?
