best antivirus and firewall, which would you recommend? Options

[initial-seven]

I have spent the last few days looking for the best antivirus and firewall. I wanted an antivirus with a high detection rate and light on resources. Also, a solid firewall.

I used to have Norton Internet Security 2005 antispyware edition, but it was a resource hog and caused my comp to freeze up sometimes. So, I just uninstalled it. For the next two weeks, I tried ZoneAlarm Security Suite because it recieved good reviews. However, it had taken quite a while to load at the taskbar when booting and the antivirus was said to have poor/low detection rates.

Some of the most recomended/popular antivirus programs that I found were:
- AVG
- AntiVir
- Kaspersky
- NOD32
- Avast

Some of the most recomended/popular firewalls that I found were:
- Kerio
- ZoneAlarm Pro
- Sygate
