There is always a trade off.

Typically, it does not matter what you decide to choose but will instead be using time on your computer to always be tweaking it and forgetting what you intended to have it for.
Zone alarm is good, but I have found Panda, even though it has to be paid for is well worth the money. You get free 24/7 tech support and $1,500.00 insurance on hardware damage if infected and damaged by virus or other malicious code. Nobody else offers these things. Norton does not catch things Panda catches, such as adware or malicious cookies, and if you try getting rid of Norton the program leaves behind awful mess in Registry. I also use Microsoft sypware defense which is free, not for any spy purpose as Panda gets all that, but for the 49 checkpoints, like guards watching vulerable areas inside computers and doesn't allow any potential harmfull changes unless you first ok them as safe. Free is just ok in my experiance, but purchasing a great Internet Security Suite is well worth the expense. I paid lots for my system why go cheap on security?
