Also add any processes you frequently use to the exclusion (like python3.5 for ranger).

Thanks for these tips. Real-time protection seems to be responsible for my laptop pegging itself at 100% CPU for a few minutes every time I wake it up from sleep, I will see if this changes anything.

TL;DR: disable win defender. Anyways, this is the first thing I do on a dev machine. Usually I remove any A/V completely, not just disable it. Because top of the line core-i7 machine with all "security" features enabled works no faster than venerable 486dx.

This also helps Visual Studio. I'd definitely just add exclusions though, rather than disabling it entirely.

  I was never able to get it work using folder exclusions or application exclusions. Turning off REALTIME protection is the only thing I am to use to get relief from this problem.

I have a shortcut on my desktop that toggles Real Time Protection: Create a file `toggle-defender-real-time-protection.ps1` in a known location with the following content: $preferences = Get-MpPreference Set-MpPreference -DisableRealtimeMonitoring (!$preferences.DisableRealtimeMonitoring) Then create a shortcut for this target: %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File "toggle-defender-real-time-protection.ps1" Make it run as Administrator. (Source of this nice script: https://superuser.com/a/1287788/25933 https://superuser.com/a/1287788/25933) Note that Windows somehow turns the protection on after a random amount of time.

I can't disable that (and other) crap on my laptop due to corporate AD policies. The only proper workaround I managed to find: BYOFD.

But why don't we deserve both speed and security, at the same time?

Antivirus is not very useful. A little common sense goes a lot farther. Whenever I use windows, I disable the AV entirely.
