I don't know what Windows Operating System you have or what edition you have of Internet Explorer.
It's purely my guess that IE is trying to update to No.11 and your system does not like it. You can check the edition of your current Browser by Clicking Internet Explorer > Help > About IE.
Furthermore, you Will find IE in your Control Panel's list of programmes.
Open the list of installed programmes and, towards the top left hand side of page, click 'View installed updates'. Search down the list of revealed up-dates and you will locate IE which can then be uninstalled....and IE will revert to it's previous edition.
Incidentally, I agree with Hopkirk..."Internet Explorer isn't the best". So, if you wish to avoid trying another Browser, it's worth trying the steps I have suggested.
