I'm still using Sygate Pro, even though those evil Symantec scumbags bought it and scrapped it in favour of their own bag of sh*te Norton thing. It's still an excellent firewall - doesn't work with Vista apparently - but I've been thinking about changing it, either for Outpost, which last time I tried it, was ok for a while then stopped all email traffic dead, or Comodo, which is free but has had very mixed reports. Any comments on either of these would be most welcome.
