Greetings.
Maybe this a question you want to consider: Do I really want a suite, or creating a defense from individual parts?
The main weakness of suites is that they seldom use the best of the breed of each of its type. Kaspersky AntiVirus might be a top notch Antivirus, but their firewall might perhaps be not to your liking. On the flip side suites can often be cheaper than assembing each security component piecemail. Also the danger of combining ependent third party security software is that the possibility of conflicts have to be handled.
Lastly, some people claim that the interconnected of a security suite is a weakness not strength because if one part of the suite goes down, everything else falls with it.
If you still decide to use a suite, here are a few of my recommendations besides ZA Security Suite (Click on them to find out more):
Panda Platinum 2006 Internet Security
McAfee Internet Security Suite
Kaspersky Internet Security 6.0
