I have the free version of zonealarm. through my work, we get access to a free copy of Trend-micro PC-Cillin, which I have duly just installed. PC-Cillin comes with a free firewall, and I have the option of engaging that or continuing to use zonealarm.

Any thoughts?

One thing is that Zonealarm basic doesn't support internet connection sharing (which I need -> I turn-off zone alarm when I'm using ICS). I'm not sure whether PC cillan supports it or not...

only hardware firewall will help you out.

In terms of what? Internet connection sharing?

Just read-up on trend micro's firewall, and it does support it, and zone alarm pro does as wel. :)

Download Pro and get a crack for it. ;)
