Firewall needed!

I need a Firewall. Is there any shareware Firewalls available out there that are any good?

Thanks

Shareware Firewall

Thanks Halo - much appreciated. l'm avoiding Zonealarm have had problems when using previously, will give Keiro a whirl.

Cheers

I use Kerio, it works very well.

 

Sygate is my favourite, works better than ZA at least

 

FireWall

I use Kerio and have done for some time now and it is both simple and effective. It's also free. I found ZA a bit too complicated and even a little arrogant to this simple old fellow.
