What is the ideal number of Antivirus a laptop should have?

Question by Esmy: What is the ideal number of Antivirus a laptop should have?
Hey everyone, that reads this.
My question is what is the ideal number of antivirus a laptop should have.

My laptop has Kaspersky Anti-Virus 2010 installed when I first got it. Best Buy had installed it.
And I just installed Malwarebytes Anti-Malware, mostly because I have this installed in my desktop and its really good.

Im just pretty much wondering if those two are ok.

Thanks.

I would prefer having 2 virus programs, reason is that even if one of them is not able to detect the virus the other would certainly detect it.

What Is A Good Anti Spyware That I Can Buy?

I need to buy a good anti spyware for my PC. I do not want anyone recommending free ones over the net; instead I am looking for one I can buy from future-shop or best buy. What are some good brands? how much do they cost? I am also running Norton in order to protect my computer from viruses; whatever I get has to be compatible with that.
