Metaslider

On my homepage http://www.wp.parsival.be/ i found the following html code.
I suggest it comes from my plugin ‘metaslider’.

But when i delete this plugin the text: metaslider id 20320 does’nt found.
How is is possible to put this sentence on display none? Or to delete it?

<div id="raindrops_metaslider" class="clearfix" style="display: block;"><!-- meta slider -->
<div style="max-width: 1280px; margin: 0 auto;" class="metaslider metaslider-flex metaslider-2030 ml-slider">

    <div id="metaslider_container_2030">
        <div id="metaslider_2030" class="flexslider">
            <ul class="slides">
            </ul>
        </div>

    </div>
    <script type="text/javascript">
        var metaslider_2030 = function($) {
            $('#metaslider_2030').addClass('flexslider'); // theme/plugin conflict avoidance
            $('#metaslider_2030').flexslider({
                slideshowSpeed:5000,
                animation:"fade",
                controlNav:true,
                directionNav:true,
                pauseOnHover:true,
                direction:"horizontal",
                reverse:false,

                slideshow:true
            });
        };
        var timer_metaslider_2030 = function() {
            var slider = !window.jQuery ? window.setTimeout(timer_metaslider_2030, 100) : !jQuery.isReady ? window.setTimeout(timer_metaslider_2030, 1) : metaslider_2030(window.jQuery);
        };
        timer_metaslider_2030();
