The old Defender user interface is alive and well in 1703. It's C:\Program Files\Windows Defender\MSASCui.exe

For your desktop icon you can't remove, try taking ownership then granting yourself full control. Right-click on it, select Properties then on the Security tab click the Advanced button. Then click Change on the window that appears. Once you are the owner, click Edit on the Security tab and add your user account to the list with full control, if it's not already there. Then try deleting it again.
