一个php的论坛，在右下角有这样的广告



其源文件下面的代码为：

</script>
<script type="text/javascript" language="JavaScript" src="js/pw_jobcenter.js"></script>
 
<script src="js/float.js" language="javascript"></script>
<script language="javascript" defer>
var oldWindowOnloadFunc = window.onload;
 
window.onload = function () {
    if (oldWindowOnloadFunc != undefined) {
        oldWindowOnloadFunc();
    }
 
    var LeftCode = RightCode = '';
/**/
    var popParam={'title':'幸运二泉网，好运天天上','winHeight':276,'winWidth':252,'winClose':10};
    var popCode='<a title="幸运二泉网，好运天天上" href="http://bbs. target="_blank"><img src="http://bbs. width="250" height="250"/></a>';
    ShowPop(popParam,popCode);
/**/
imgloops.imginit();/*多图片轮播*/
}
</script>
<script language="JavaScript" src="/js/pw_init.js"></script>

如何让电脑上不显示这个小广告啊？ 每次刷新都有，看的很心烦
