Windows 11, like previous versions, comes with Windows Security – a built-in antivirus to help keep your PC safe out of the box. Formerly known as Windows Defender, Windows Security offers reliable protection and enough features to keep your PC safe in more ways than one. But it’s far from perfect.
How to Disable Microsoft Defender Antivirus in Windows 11
If Windows’ native antivirus is proving to be an annoying nuisance that you’d rather not have around, it might be a good idea to disable it. In this guide, we’ll discuss some common reasons to disable Windows antivirus, and some ways to disable it temporarily and permanently.
The most common reason to disable Windows Security is when it starts marking certain files as a threat and blocks access to them. If you know these files are safe and you want to keep the antivirus program from getting in the way, temporarily disabling them is the only solution.
The Windows Security antivirus is also quite resource hungry and on older systems your system will feel the crunch when it is running in the background. Windows Security also becomes redundant when a third party antivirus suite is also installed.
