Loading a insecure script on my blog page

Hi, I’m using your plugin on my site https://extremepedia.com/, but I’m having trouble loading one of my money-making articles https://extremepedia.com/best-inflatable-kayaks/, which isn’t loading completely. So I called my web host, who informed me that the page is running an insurance script ( http://classic.avantlink.com/affiliate app confirm.php?mode=js&authResponse=c93f2380fcafac06a5d9fd8fa9c15990c480dc39 ) that is creating the loading problem. Could you please assist me in resolving this?
