No probs, Davy. To be honest, until Sygate messed it up with the upgrade, their product was the only firewall I was prepared to tolerate.
However, as I posted earlier in this thread, I have downloaded and installed Zone Alarm version 2 (around circa 1999) on a friend's nieces machine and, having called at her's to check on it a couple of times, I have now put it on my main machine. It does just what I think a firewall should do (puts the PC in stealth mode and only lets applications access the internet that YOU have allowed) and nothing more. It doesn't have popup blockers, cookie managers, content managers etc. that any decent web browser will allow you to configure yourself, nor does it control and quarantine e-mails, which any decent email checker will allow you to do yourself. I could go on and on but, to put it simply, it allows you to take back control of your computer, control that you surrendered when you installed a modern software firewall.
As I have said before, this computer is mine, not Kerio's or Sygate's or Outpost's. If I want it to be controlled by someone else, I might as well leave it open to hackers and save myself a lot of faffing about.
