What does EMET do exactly? How does it add security to your system? I would think if it adds security and causes no problems, Microsoft would just add it as a feature of Windows by default, so I wonder if there are cons to it. What are Pro and more importantly Cons? Does it interfere with programs and cause problems for some legitimate programs and processes? Is it mainly for legacy software that is not updated, and not really beneficial to new actively updated software (Chrome for example)?
