I would go the same way as Tootech. As said, there are both advantages and disadvantages of using an Internet Security Suite.
The advantages are that you don't need to look out at various programs for performing specific functions and a single application keeps you safe. However, this very thing can be a disadvantage too as once disabled, all your protection is disabled and you become more vulnerable than ever.
Just choose what you find the best to your needs and all should be fine. :)
