找到下面的函数，大约在29行
function system_information($data) {
$update = pc_base::load_sys_class('update');
$notice_url = $update->notice();
$string = base64_decode('PHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPiQoIiNtYWluX2ZyYW1laWQiKS5yZW1vdmVDbGFzcygiZGlzcGxheSIpOzwvc2NyaXB0PjxkaXYgaWQ9InBocGNtc19ub3RpY2UiPjwvZGl2PjxzY3JpcHQgdHlwZT0idGV4dC9qYXZhc2NyaXB0IiBzcmM9Ik5PVElDRV9VUkwiPjwvc2NyaXB0Pg==');
echo $data.str_replace('NOTICE_URL',$notice_url,$string);
}第一种方法：将$string的值更改为：
$string = base64_decode('PHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPiQoIiNtYWluX2ZyYW1laWQiKS5yZW1vdmVDbGFzcygiZGlzcGxheSIpOzwvc2NyaXB0PiA8ZGl2IGlkPSJwaHBjbXNfbm90aWNlIj48L2Rpdj4=')第二种方法：将$notice_url的值设置为空即可
$notice_url = '';
第三种方法：注释所有的代码，并将最后一行修改为：
function system_information($data) {
//$update = pc_base::load_sys_class('update');
//$notice_url = $update->notice();
//$string = base64_decode('PHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPiQoIiNtYWluX2ZyYW1laWQiKS5yZW1vdmVDbGFzcygiZGlzcGxheSIpOzwvc2NyaXB0PjxkaXYgaWQ9InBocGNtc19ub3RpY2UiPjwvZGl2PjxzY3JpcHQgdHlwZT0idGV4dC9qYXZhc2NyaXB0IiBzcmM9Ik5PVElDRV9VUkwiPjwvc2NyaXB0Pg==');
//echo $data.str_replace('NOTICE_URL',$notice_url,$string);
echo $data.'<script type="text/javascript">$("#main_frameid").removeClass("display");</script>';
}修改完成后替换服务器上的文件，就不会在检测更新。
