it IS possible to remotely configure the firewall [Note: Connection to a remote administration is allowed by the internal Kerio Personal Firewall policy. This means that it is not necessary to define special network security rules to enable remote administration]: but this can be prevented by setting a password I believe

not sure, but it sometimes to seem to cause quasi-freeze or great slowing in Win98. For example when I click on certain links that have downloadable stuff or PDFs.
100% harmlos die funktionen sind normal
I have 2 identical looking processes like this, and one can record keyboard inputs.
Can be used to configure the firewall from a remote computer
I got it after installing kerio 4
I also have 2 of these processes (yes after installing kerio4)

keine ahnung ! is es nu gefaehrlich oder nit ?
Spyware? -MAYBE. From time to time a remote internet server (Kerio?) tries to connect to my computer. However I am able to block the attemt via firewall settings
All I know is that your computer is at risk. I have been remotly admin. several times. Block it from running.
With this installed on my computer, crashes, slow downs, and minutes are wasted just wait for windows to shutdown. I'm sorry I purchased this software and I'm going to use a different firewall.

Just Installed sunbelt. 2 instances doesent use much memmory or CPU power
Kerio Personal Firewall - Takes up alot of CPU time - more than anything else
Purchased Firewall - great software
Doesn't work well in Vista. Connection easily saturates and stops responding after a while. Uninstalling is more involved under Vista than it was in XP.
