same can be said for android in a sense though, got to install advanced task killer, juice defender and now anti virus software

You don't "need" to install any of them, using advanced task killer is silly and totally not needed on android as its capable of managing apps on its own and randomly killing them messes it up.

Juice defender isn't needed if you set your phone up properly and there are much better apps that do far more and save more battery.

As for anti virus, don't even go there

android antiviruses have never worked in my experience. No need to install advanced task killing stuff as the normal task manager can stop everything anyway!
