Symantec Vulnerability Protection Add on

I do not have an Intrustion Prevention policy in my SEPM installation yet when I push out 12.1.3 clients I am noticing the Symatnec Vulnerability Protection add on is being installed in Internet Explorer as well.  I am on the understanding that this add on is part of IPS.

I have verified my Install Feature set does not enable IPS.

How can I stop this add on from being installed?
