Thanks! However, I am still wondering about any potential conflict with Avast! 5.0.677 and Spybot Search&Destroy 1.6.2.

Nice but it would be helpful if we could know the level of protection offered by each one. How effective are they? What kind of testing is available to insure the proper operation and configuration? Also some of these purport to be smart firewalls, so can any of them respond to an attack and indicate to the user some configuration that needs to be adjusted?

Does Zone Alarm Free work in 64-bit Windows 7 Ultimate? Also, will there be any conflict with the other 2 free anti-malware, viz., Avast 5.0.677 and Spybot Search&Destroy 1.6.2 that I use?

# This file describes the network interfaces available on your system

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

auto br0
iface br0 inet static
address 192.168.0.1
netmask 255.255.255.0
post-up iptables-restore /etc/iptables.up.rules
bridge_ports eth1 wlan0

iface eth1 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down

iface wlan0 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down

Yep! I am using my own iptables script to flush and recreate the rules as soon as my external interface is up! happy

Umm....Try it again with your review of COMODO! You just misled any of your readers into thinking that if they want Comodo's anti-virus, they have to buy the PRO product, when in fact, they can get COMODO Internet Security with antivirus as a totally FREE product! The Pro product adds 24hr. live PC support and a WiFi protection toolkit called Trustconnect! I've been using their free products for a while now, and have had zero problems! It's easy to install on anything from XP to Win7! The free download is at:

Next time check your facts! wink
