After i did my pc cleanup yesterday using bitdefender, I can sign in to my outlook.com live account.. However, all the icons and backgrounds are missing..

I tried to 'View page info' in Mozilla Firefox and under the Media section, things like (https://a.gfx.ms/OLFav.ico) and (https://a.gfx.ms/OLHdrLogo.png) are with unknown size and 0px x 0px dimension..

I tried using all other browser like IE and Chrome and end up the same thing.. I could not click on anything except sign out..

Please give me suggestions of what to do. Thank you
