Man, after much confusion and frustration over whether not Sygate was a good combo with Webshield, I decided to uninstall Sygate and try out Kerio. I’m sticking with Kerio. The default settings are all I need out of a firewall and it works great with Avast thus far. Sygate is history on my machines.
I used both Sygate Pro and Sygate Free with the same controversial problems associated with both of them. Sygate bad. Kerio good. Avast Webshield good.
Welcome to the dark side! 
John (another happy Kerio user)
And 4.2 is coming in the next few days!
Plus if you use the free version, you get the FULL firewall product, including intrusion detection. Sygate free isn’t the full firewall.
I have to agree with you , Kiero looks a winner. ZA and its lousy memory can go jump 
Another “dark-sider” here.
I’ve run Kerio with Avast on the PC since version 4.0.8 and am currently trying the latest Kerio 4.2 beta 4 which has given no problems either. I think everyone will like the new update.
After several ZA debacles, I’m happy with Kerio and Avast which is, of course, my favourite AV!
Happy days

I am very happy too, running Anast 4.6 with Kerio 4.2 Beta 4.
Non problem. All work smooth and fine. And memory usage quite normal.
I 'll stay with both of them.
Is there any information about final Kerio 4.2 release?
Thanks Alwil and Kerio. Great Job!
Have a nice day!
Dark side of Kerio. Switched to 4.1.3 and had the same problems I encountered with 4.2B4-Kerio doesn’t always load at boot . Saw a few other messages about this on their website. No solution-don’t know what the conflict is. In spite of being installed as an automatic service under XP SP2, it just comes up partially at boot (based on “protect a startup and shutdown being checked”) and then goes away, never to be seen again, until you start it manually. Also tried putting it in the startup folder;didn’t help. Happened only occasionally with 4.1.2. Watch carefully to be sure KPF 4 is really running if you plan to use it. No comment from their forum on the questions about it. Sygate is looking better again, unless Kerio comes up with an explanation/fix.
Is the WinXp firewall accidentally on.
No; it is disabled. Actually, I cheated a bit and am trying out KPF 2.1.5 as an alternative, but this was not a problem on 4.1.2; just cropped up on the 4.2 beta and now 4.1.3.
I’m using 4.1.2. Thanks for the input.
You’re right. They’re not much help on the subject on the Kerio board. I won’t update my version until they resolve the bug.
Sded, won’t be ZoneAlarm an alternative?
I used ZA for five years, changed to Outpost, went to Sygate and come back to Outpost.
Tried Kerio some time ago but version 4 seemed to much ‘bloatware’ for me… Maybe just an impression.
I used ZAF, ZAP, ZASS but found they didn’t provide adequate logging or display insight into what was happening or how things should be configured. One use of a firewall is for figuring out what should/shouldn’t have been blocked/allowed, and ZA never really helped me. But try the newest ZAF and see if it suits you. I am trying out Kerio 2.1.5, and so far seems fine. Like the KPF4 GUI, but don’t understand the startup problem at all. Must be a conflict with something, but I don’t have a complicated system and don’t see any effort on the Kerio forum to help solve the previous comments on it.
You’re right… For ZoneAlarm, I always consider VisualZone (http://visualize.phenominet.com) a must have complement.
Unfortunatelly (or not ;D), no other forum can give you the same support as here
Agree, places like Kerio specifically don’t do official forum support for their free versions, in spite of the fact they could point to it in their pay versions as “50K hours of beta testing” or some such. Oh well, wait to see what happens on Kerio. In the meantime, if you want to try it, a good free version of Kerio 2.1.5 is available at http://www.dslreports.com/forum/kerio along with a prebuilt set of rules to modify if you like. Will report back after trying it for a bit.
Not that it’s overly relevant, but I’ve been using Kerio for many months and I’ve used a number of beta versions including all of the versions released recently and I’ve had no problems like that at all with Win XP Home SP1 or SP2.
It shouldn’t be too hard to figure out what application is causing the conflict. Just stop everything but KPF from starting and slowly add apps back to your startup list. However, I have a feeling that you’ve done this already and weren’t able to determine the culprit. Is that the case?
I’m planning on switching to Kerio too. I’ve been happy with Sygate, but … Kerio looks like it offers more what I’m looking for in terms of fine-tuning control. I haven’t decided whether to wait for 4.2, or go ahead and install either 2.1.5, or 4.1.2 or 4.1.3.
No probs with 4.1.3 here 8)
Tried to isolate the interfering program; no luck. Problem is that it doesn’t happen 100% of the time, so is probably load order dependent. Easier to switch than spend any more time trying to diagnose it. It simply shouldn’t happen to a firewall, ever-makes me wonder about probable malware vulnerability. And I wouldn’t know what the next interferor might be. I never saw any of the others who had the problem come up with anything either, or any comments from Kerio or the peer support group on it. So far KPF 2.1.5 is a fine replacement. Or Sygate is acceptable, in spite of its PITA characteristics. No reason not to use KPF 4 if you have no problems. Just a warning to KPF 4 users to watch out for it occasionally not loading-assume easily noticed if often not loading.
Will it help if you use Startup Delayer to control the order of programs load?

Thought about the startup delayer, but decided that was too much trial and error vs switching, And still worried about the next problem program for Kerio. Thanks for the suggestion, though. Will probably see if Kerio has any suggestions, otherwise stay switched to something else. Even a small unreliability is unacceptable in a firewall, and I would find it hard to trust KPF 4 again without some real solution.
