Nothing Happens when icon clicked

A new windows 10 PC . Shortcut was working correctly till yesterday.
Today it flashed a message saying you buy McAfee Antivirus or use Bitdefender
No other choice . So bitdefender was selected.

Now clicking shortcut did nothing.
If ran as administrator it ran.

Solution:
Right click shortcut. Select properties. Added a user and gave full control rights.
It started working.
