There are several ways – choose the one that is suitable for you.
Microsoft has not without reason integrated antivirus into its OS: this tool protects the system from malicious programs from the moment of its first launch. Therefore, Windows Defender, which is also called Windows Defender or Windows Security, is a useful function necessary for most users.
However, sometimes this antivirus has to be disconnected. For example, periodically Windows Defender interferes with opening the programs you need, and in Windows 11 it also constantly loads the processor by searching for threats in real time. After all, if you prefer a third -party antivirus, then Microsoft protection can conflict with it.
Typically, the built -in antivirus is turned off after installing a new one, but sometimes this does not happen and the protective equipment begins to interfere with each other – they slow down the system or see in each other unwanted. That’s what you can do about it.
How to disable Windows Defender in different versions of the OS
If you need to start any program, and Windows Defender mistakenly considers it harmful – you can turn it off directly in the settings. This option is suitable for Windows 10 and 11. It is easiest, but allows you to deactivate protection only for a while.
1. Open the Start menu, click the “Parameters” and go to the “Privacy and Protection” section → “Security Windows” → “Protection from viruses and threats” → “Protection Parameters” → “Management” → “Managementsettings “.
2. Disconnect the parameter “Protection in Real Time”.
For some time, the antivirus will cease to respond to your actions, even if you work with files that he considers potentially malicious. But, as it is written in the warning next to the “Protection in Real Time” parameter, then Windows Defender will turn on automatically.
