Note 9 app failure

[Zain90]

I am having one difficulty in using McAfee in my note 9 which I recently bought.
Each time I am installing an app,there's a message which is popping up in the scree saying "macaffe has stopped".
Any suggestion folks ?

Samsung phones already has McAfee security pre installed. Check device care for more information.
