Well, Many of you may be amazed with my answer. :P

I am just having KIS 2010 on my system with nothing else. I do run manual Malwarebytes free edition scan often say in 2-3 weeks etc, but apart from these two, nothing else.

Perhaps the reason being, I am aware of safe ways to use my system and the way Viruses etc get into system. So KIS is just good enough for me.
