Which anti-virus is good for pc ?

Well i'm using a indian brand called NPAV since 2 years, its really good. it never slowed down my PC

quickheal total security is best antivirus for pc and quick heal technical team support for every issue, and new virus

I am using Microsoft Security Essential from past one and half year and hasn't been facing any issues. The only thing is that we need to update it periodically which normally takes few minutes if you update regularly. 

NPAV as an option is really good. I had it in my previous workplace computers. Works like charm.

I think Quick Heal total security is best Anti- virus ,

I am using it for last three years. 

ESET Smart Security

Using Microsoft " Windows Defender " It's Free if you have a Genuine Version of Microsoft. Used Many Antivirus & Internet Security Softwares before , I feel that " Windows Defender " is the best option.

Thanks to all for your valuable contribution...

NPAV is Best
