Microsoft announced a security flaw in Internet Explorer for which they don’t have a patch yet. This issue allows a hacker to access your computer with the same rights that you have, while you’re viewing videos in Internet Explorer.
Microsoft has a workaround in Knowledgebase article 972890. However, you can also use an alternative browser such as Firefox or Chrome until Microsoft has the patch ready. They’re working on the patch now, and should have it out soon.
