First Understand how ad blockers work..

When a browser requests a website address it downloads the corresponding HTML file which includes internal & external references to Javascript files, CSS stylesheets and images. If the browser has an ad blocker installed, it will compare the names of referenced scripts & files against a "block list" and if there are any matches those files will be ignored.

To fix this problem, here i am providing a small solution.

Create one "ads.js" file on th root and place the below code in that file. 
var canAdsRunOnThisSite = true;

The following code add in between Head tags (<head>...</head>). 
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js" type = "text/javascript"> </script>
<%--Ad Block Code - JS - Start--%> 
<script src = "js/ads.js"> </script> 
    <script>
	$(window).load(function () {
		if (window.canAdsRunOnThisSite === undefined) {
			// adblocker detected, show message
			$("#notify").show();
			$('#top').animate({
				'height': $(window).height(),
				'position': 'fixed'
			});
			$('#adblocktext').fadeIn('1000');
			$('#alt').click(function () {
				$('#top').animate({
					'height': '50px',
				});
				$('#adblocktext').fadeOut('1000');
			});
		}  
	}); 
</script>
<%--Ad Block Code - JS - End--%>

In the Body content, at last add the following code. The below code i have added in this website. 
<div id="notify" style="display:none;">
   <p id="adblocktext"> <br />
