Help How important is VZ Security app?

[beowulf7]

I noticed that our S4 comes with the optional VZ Security app and is free or $2/mo. (depending on how much "protection" you want). According to p. 112 of the S4 manual, this is what it says about VZ Security:

The Verizon Mobile Security application helps protect your
phone from digital threats, including viruses and malware,
and from people accessing the information on your phone if it
is ever lost or misplaced.
Verizon Mobile Security helps keep your phone secure and
protected from viruses, malware and risky web sites.
Important! Data charges apply when using VZ Security.
 From the Home screen, select Apps ➔
VZ Security.

How important is it and what kind of overhead will it put on the performance of the S4? So far, I haven't activated VZ Security. My S4 is also rooted, so if the majority of people here say it's just bloatware, I'll freeze it with Titanium Backup. TIA.
