This does not happen if you’re running a third-party antivirus app. There’s no real fix for this, but if for whatever reason you vì want to lớn keep real-time protection off, but we bởi have a kind of work-around for you.

Stopping the Windows Defender Service or Uninstalling Defender
There are tips floating around out there for stopping the Windows Defender service from starting automatically when you start your PC, & even a complicated process for completely uninstalling Windows Defender altogether. We don’t recommend them. Here’s why.
First, if you disable Defender—or it gets automatically disabled when you install a third-party app—it actually uses very few system resources. There’s really not much point in stopping the service. This is particularly true in Windows 10 where you can disable the real-time protection, but still have the added safety of using Defender for manual scanning as a back up to lớn your regular antivirus app.
