Out of all the security softwares mentioned, I have used Norton and Kaspersky in my computer system and found Kaspersky more powerful. I have seen McAfee on my friend's laptop but haven't personally tried. I am happy with Kaspersky...

Norton is biggest ram cruncher after than its Bitdefender good but also takes ram and more activity where Kaspersky is light weight dont ask about McAfee i had bad experienced with free version ,ram consumption is low but no security against tread

Kaspersky Internet Security 2010 has everything you need for a safe and secure Internet experience.
