What is Windows Defender?

Windows Defender (now known as Microsoft Defender Antivirus) is an always on, anti-malware software that guards your computer from external threats. The antivirus is developed by Microsoft to protect computers from virus threats that are running the Windows 10 operating system.

This antivirus comes preinstalled with any version of Windows 10. Windows Defender protects your computer in realtime from not only viruses, but also ransomware, rootkits, trojans, spyware, and many forms of malicious attacks. The program is free to use, and Microsoft sends regular updates on Windows 10.

Why turn off Windows Defender?

Good question you ask! If Microsoft Windows Defender is a free antivirus that protects your system from malware attacks, then why would anyone feel the need to disable it or turn it off? There are however specific cases where you would want to disable the Windows Defender.

You may want to install specific software or program on your system, but Microsoft Windows Defender in Windows 10 might keep interrupting. Take 3rd Party Software as an example. Windows Defender can treat programs or applications from small developers as a threat, and it will not allow you to install it. This can sometimes be helpful as you don’t know if the software is legitimate or it may contain some form of malware which may breach your security.

Nevertheless, sometimes you’re sure that the software is safe and legitimate and want to install it, but the Windows Defender keeps deleting it. In this case, you might want to disable Windows Defender temporarily.

There may arise a case where you don’t trust the capabilities of Microsoft Windows Defender and decide to install a third-party antivirus for virus threat protection. There are numerous third-party antivirus programs on the market that can be used in place of Windows Defender.

One benefit of installing a third-party antivirus is that it gives you more security and control over it. You can disable it at any time and re-enable it again.

You may also want to disable Windows Defender in Windows 10 as it utilizes a lot of resources when it runs in the background. You may not have enough ram, or you may want the processor to focus on some specific task rather than waste resources on scanning your computer.

These are just a few reasons for disabling the Microsoft Defender antivirus.

Whatever your reason may be, Microsoft Windows Defender in Windows 10 is still a valuable resource. Something is better than nothing, meaning your computer is much more prone to being infected while using it with the Defender disabled. If you’re planning to use another antivirus, then disabling the Windows Defender is justifiable. The Defender antivirus does not have a disable or uninstall option anywhere. Keep in mind that when Windows Defender disable, the security of your computer will be at risk of malware attacks.
