Sometimes websites don't look like you expect them to–images might not appear, menus might be out of place, and text could be jumbled together. This might be caused by a compatibility problem between Internet Explorer and the site you're on. Sometimes this can be fixed by adding the site to your Compatibility View list.
One possible explanation: The site might have been designed for an earlier version of Internet Explorer. If Internet Explorer recognizes that the webpage isn't compatible, you'll see the Compatibility View button on the Address bar. Try clicking it.
To access the Defender Management Portal, you can use any of the following Web browsers: - Chrome 15 or later - Firefox 8 or later - Internet Explorer 9 or later (Internet Explorer run in compatibility mode is not supported) - Opera 11.1 or later - Safari 5.1 or later.
If you wish to keep Compatibility View enabled you can remove the Defender Management Portal from the Websites list.
