Topic: Anti-Virus vs. Internet Security

[B2C-Max Lazer]

I'm building myself a new PC, but, as my dad reminded me, I'll need a security program as well as office suite etc.
I suppose Office 2003 won't work with Vista
Anyway, I've been looking at anti-virus programs, and the two that have mostly caught my attention are Kaspersky and BitDefender. Both look to be overall great products, but both have me pondering the same issue.
BitDefender's website seems to shed a bit more light on this, but not as much as I'd like.
BitDefender's Internet Security, according to their charts, does the same thing and more than their antivirus. This puzzles me, as there is even a "total security" version.
 
So basically, the question is, do I need to buy both Anti-Virus and Internet Security packages (or in the case of BitDefender, the "Total Security," perhaps), or do I only need one or the other?

already used those both anti.virus and lemme tell u that kaspersky is betther in anything, and it occupies less space ( i think)

but atm i am using ESET Smart Security is good new and cleans everything

Actually.. I wouldn't really run one in the background. They take up so many resources. I use AVG, but have disabled the auto agent.. I just manually run the virus checking software every so often. I also use Microsoft's built in firewall as I'm running XP 64.. but putting your computer behind a firewall is the safest route to go. Not with so many resource hog programs.

Hmm...interesting, as I've read that Kaspersky and BitDefender, along with the other top brands don't take up too many resources. Much unlike Nortan Anti-Virus.
