I saw Windows 8 64 bit system has its own built in firewall. Compared with Kaspersky, if this firewall has the ability to keep all virus or malware out of my computer?

I always love firewall instead of anti-virus. Because firewall prevent virus or malware come into computer, but anti-virus is to kill the viruses in computer.

But I dont know if windows 8 64 bit firewall can really take the job or not.

I'd prefer to install Kaspersky Internet Security on my Windows 8 in terms of Windows 8 firewall sometimes can't prevent those dogged malwares.
