    Any way to permanently disable automatic scans in Windows Defender?

    The stupid thing is set to perform a quick scans every day. I'd have to spend all my time downloading the most vile porn from sites in the darkest depths of the internet to need my AV to automatically scan my computer this often.

    I've disabled the auto scans in task scheduler, but they get turned on again after every Windows update, which is a nuisance. Is there some way to make this setting stick permanently?

    I am a power user and practice safe browsing. The AV is just there as a precaution, I don't need it performing scans 24/7 without my approval.

    I know it stops the scan when I take the computer out of idle, but I don't want it doing anything without my approval.

    Or is my only option third party AV?

    I have Windows 10 Home Edition.

    Sadly no. This is an issue with Windows Defender running a daily scan rather than third party software (there is no built-in setting to control Windows Defender scan frequency as MS doesn't trust us with that much power). It's built into Windows 10. It's supposed to run a scan at least once a day when the computer is idle.

    A workaround I tried just now is to set the task condition to only run a scan if the computer has been idle for 1 hour (that's the highest it can go). We'll see if this setting sticks after a Windows update or if it resets as well.

    I hope that "Trigger" won't be affected by updates.
