Hi hassanaljerf
I am Louie, a Microsoft Community member and a fellow Windows 10 user like you. I hope I can help you on your concern.
Could you please try turning off the User Account Control Settings it can be done in Control Panel or in Registry. and check if it will allow you to open Reputation-based Protection this time.
In Control Panel:
- Type UAC in the search field on your taskbar.
- Click Change User Account Control settings in the search results.
- drag the slider down to Never notify and click OK.
- Reboot your computer for the change to take effect.
In Regedit:
- Type REGEDIT in the search field on your taskbar.
- Click REGEDIT in the search results.
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies
- Select System.
- Find and doubleclick EnableLUA
- Change its Value data to 0
- click ok.
- Reboot your computer for the change to take effect.
Sincerly
Louie
