The U.S. Department of Homeland Security has issued a warning advising Americans not to use Internet Explorer versions 6.0 – 11.0 after a security flaw was discovered. The security flaw allows hackers to use a corrupted Adobe Flash file to bypass the security protections found in Windows operation systems, and could allow for unauthorized remote code execution. Homeland Security suggests that people should use an alternate web browser, (FireFox, Chrome, etc.) until a fix can be found.

FireEye, the Internet security software company that discovered the bug, recommended disabling the Flash plugin in Internet Explorer to prevent the bug from functioning. Microsoft is working to fix the problem, and has provided additional possible workarounds on their site.
