Kerio Personal Firewall is a small and easy to use system designed for protecting a personal computer against hacker attacks and data leaks.
It is based on the ICSA certified technology used in the WinRoute firewall. The firewall itself runs as a background service, using a special low-level driver loaded into the system kernel. This driver is placed at the lowest possible level above the network hardware drivers. Therefore, it has absolute control over all passing packets and is able to ensure a complete protection of the system it is installed on.

What's New?
- added Dutch translation
- automatically uses the most suitable help file depending on the selected language
- KPF is now able to analyze kernel dumps and determine, whether crash was caused by KPF
- KPF now attaches its registry settings to crashdump
- if AVG 7 is detected during first KPF start, apropriate application rules are created automaticaly (support for AVG bundle)
- fixed minor popup killer bugs and improved its functionality (catches showModelessDialog and showModalDialog functions)
- traffic chart is not cleared when gui is closed
- changed update server's and registration server's address resolving so it won't trigger automatic dial on Windows 98 ('Generate crash dump' checkbox must be disabled)
- changed new adapter handling - adapter is detected again, when user deletes it from trusted zones table
- fixed proxy server detection on NT/2K/XP
- fixed several minor bugs (packet filter editor, DNS resolution, KPF closing)

1) You have alert user under the advanced packet filters
2) You never create rules for apps
Try going into the configuration panel, click overview -> preferences tab, and exporting the settings next time (importing after you upgrade of course). It may help, I dunno.
And does it use a lot of CPU?
Personally I use Sygate, you might want to look at that too, but Kerio is good.
Just keep in mind these rules-based firewalls require you to configure certain things manually, it's not all dumbed down and hidden away like in Zone Alarm.
I dont need no zonealarm clone ;/
