Without a doubt, i would rule out Zone Alarm. There a no real plus to this suite and it just doesn't play in the same league. As for the other ones, these are all solid reputable products that are highly regarded. So as long as you use their trial to check out how well it works on your computer, you can't really go wrong.
As others have mentioned, there is no "best" AV. But if you want a short answer based on my opinion, i would without a doubt choose Emsisoft. It's the best protection you can get and i just love how straight to the point their product is: excellent protection, light on the system, respect your privacy and has amazing support. My second choice would be Eset for more or less the same reasons, but it's not on your list.
Regardless, here's my thoughts on each products:
Emsisoft Anti-Malware
Amazing detection and zero day protection, straight to the point antivirus with no "extras" and other bloatware. It's light, it's efficient and just works. Their support is one of the best in the industry.
Bitdefender Internet Security
Among the best protection you can find out there, so good in fact that many other AVs uses their engine (F-Secure, Gdata, etc...). Their license pricing is excellent. On the downside, it can be quite heavy on some machines and is lacking options in the settings. It's also considered as one of the most buggy AV (but works very well for others). Their support is really poor.
Kaspersky Internet Security
A highly regarded product as well. Also, if you go for their Total Security, it is the one that offers the most "extras", so it's a good choice for those that loves having the most features in one product (personally i don't). Support is okay, but that depends on the country.
Norton Security
One of the oldest company in the industry. There are still a lot of people (mostly noobs) that hate this product for being bad a decade ago, but today Norton is a good product. Good protection, decent set of features, honest pricing with protection for up to 10 devices. In my opinion, it is slightly behind the others mentioned, but not by much. Support is good.
Anyway that's my opinion on these products based on my experience and knowledge. The best way to know what product is best for you is to try them. Enjoy their trials (30 days for most products) and test those yourself. Not only will your choice be informed, but you'll also learn how these softs works.
