Hello,
I have updated my Win10pro to this buggy Creator Update , the "Great Windows Defender" gave me a PITA, I managed to kill this "piece of junk" by:
1. change service "SecurityHealthService" autorun to "manual" by reg-fix:
Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SecurityHealthService
Value name: Start
Value: change from "2" to "3"
2. Reboot, this stopped WD for me, but EEA didn't want to work, not uninstall nor update, so I had to do clean install 6.5.xx....
3. Reboot to SafeMode, then I run esetuninstaller.exe , removed all Eset software (I had ver. EEA 6.3.xxx & RemoteAgent)
4. Reboot to SafeMode again, and check f all eset products are removed using esetuninstaller.exe
5. Normal reboot, install EEA 6.5.2107.1
