SYM16-008 - how do I make sure I am secure.

Hello - yesterday Symantec put out advisary SYM16-008 advising of the latest threat and how to make sure you are guarded against it.  The advisory states that the solution is to update to Sym Anti-Virus Engine v 20151.1.1.4.  How do I check to amke sure I have that on my workstations and SEPM?

THANKS
