Microsoft updates EMET security tool to solve compatibility issues, harden exploit mitigations

The compatibility issues affected popular applications including Internet Explorer, Adobe Reader, Adobe Flash, and Mozilla Firefox when EMET mitigations like Export Address Table Filtering Plus (EAF+) were applied to them.
