Antivirus Software for Mac

I’m new to Mac with my recent MacBook Pro purchase. I’ve bought Guide to Switching to the Mac which is a very good reference!

I hope this is not a stupid question. I’ve been searching online and found most people think there is no need to install antivirus software in Mac OS.

But still some said it’s a good protection so it’s good to install such software. And among all available, it seems that people generally think Mcafee and Norton are both huge monsters which eat up a lot of resources. And people think Intego’s products are the best.

Any advice?
