Security firm FireEye has discovered a security flaw in Internet Explorer, particularly version 9 to 11, that lets hackers gain full access to your computer. FireEye said the active exploit also targets Adobe Flash and it lets hackers install programs on your PC, view and delete information, etc. by just visiting a site. A quick remedy is to stop using IE and opt for Chrome or Firefox. But if you are sticking with IE, Microsoft has published advanced methods you can use. There is no patch at the moment but Microsoft is reportedly working on it.
