Hey Bhushan,

You Can Use Below JavaScript in your Visualforce Page 

This script will show warning whenever you are moving from the vf page, you can add filter condition if you want it only for close

Code Below :
  
<script>
window.onbeforeunload = function(e) {
    return ' Your Desired Waring on Page Close.';
};
</script>
