How to Turn off Windows Defender on Windows10 [A Complete Guide]
Windows Defender, now called Windows Security, is the default anti-malware program that comes with Windows, protecting against viruses, ransomware, spyware, and other malware, as well as hackers. It's a reliable alternative to other antivirus software, but you may still want to turn it off occasionally.
This guide will show you how to disable Windows Defender on Windows 10.
Why Disable Windows Defender on Your Computer
Here are some common reasons that people need to disable Windows Defender on Windows 10 temporarily or permanently:
- To install another third-party antivirus program like Bitdefender or McAfee on your computer, you need to disable Windows Defender. This allows the new antivirus software to function properly and provide real-time protection against malware.
- Windows Defender is flagging a legitimate application as a potential threat, causing installation issues. This can happen when the application's code or digital signature is not recognized or is outdated, leading Windows Defender to block the installation. To resolve this, you can try adding the application to the Windows Defender exclusion list or updating the application's digital signature.
- Some system settings on your computer conflict with Windows Defender, and you need to disable it to fix the issue.
- You don't use Windows Defender as you already got another powerful antivirus program on your computer.
Unfortunately, it's not possible to completely uninstall Windows Defender from your computer, so the only option is to disable it instead.
