Is it good to have 2 securities on my computer?

I have recently been informed that AVG antivirus free edition does not have rookit protection, but on other thing it does. Before, i had a bunch of stuff from a game. I got 3 securites STP zilla, spyware doctor, and AVG. But they soon intercepted. I ahd to delete zilla, and spyware doctor. So is it safe and good to have 1 more security?

Well,it’s not good to have 2 securities at a time because they will conflict.
