Bing browsers security problem on Iphone

i have notice that when i use the Bing browsers and click on a news link if it has a video it auto plays and you can not stop it . the only way is to close the app and there is no setting in the Bing app to stop it from auto playing . this mean if someone has embedded malware or virus in the video it just loaded on your Phone. MS dose not care there help site is useless
