I was Kerio Personal Firewall user on my Windows XP system for many years but after change to Windows 7 I can't use it any more so I am looking for KPF replacement (preferably with built-in HIPS and learning option). Currently I am mostly looking at Jetico Personal Firewall and Privatefirewall - both are free to use, no longer updated and (as I read in many opinions) very good. JPF "seems" a "little more complicated" than PFW but I do not care about greater difficulty in learning curve and I am not afraid of "many popups" as long as it comes to better security of my PC in the end. There is also the question of updates for JPF/PFW - I know that they are maybe "not so important" (Windows 7, the system I am using, is fully supported by both) but still. That's why I am also thinking about Simplewall and Windows Firewall Control - these are probably best "still updated" firewalls I found - but they work in very different way as they are kind of "overlays" for Windows build-in firewall. Are they worth to use? Are they better/worse than JPF/PFW? After many days of reading opinions (also this forum) I can't still decide "which one is better". My main problem is that I can't find any "direct comparison" from the user of JPF and PFW - only separate opinions from users of each of them. I would be very grateful for any feedback and opinions if you use or know any/all of these. PS. Is using "virtual PC" a good option to do some tests of these firewalls? I'm thinking about VMware Workstation Player or VirtualBox.
