Best Free Firewall software for Windows 10

8 Comments

  1. Personally i use Online Armor Free and i think Comodo firewall and Online Armor are the two best out there…..both of them have strong HIPS…..

    Ashampoo firewall is discontinued product, it doesn’t support windows 7 at all and you forgot two great free firewalls…..Privatefirewall and Outpost free firewall…..although you can’t get separate setup file for outpost firewall free….you need to install outpost security suite and disable Antimalware component during install….

  2. Comodo firewall is the bomb, very light on the system not a resource hog and runs great with Eset Av. Defo the best.

  3. I found this thread REALLY late, but I’d like to mention re Privatefirewall. My Windows 7 Home Premium SP1 64 bit has issues with a Comodo FW kernel access driver (random BSODs); earlier in 2013, I checked 10/2012 Matousec report on FWs, found Comodo #1 and Privatefirewall #2; tried and have kept using Privatefirewall without OS/AV issues…but at each startup/restart, Privatefirewall (on its own untouchably set autorun) would cause a long blackish-screen hang between “Starting Windows” and LogIn screen, then take some time to load itself after logon. Recently I used Performance troubleshooter to not have Privatefirewall run startup; no change to hangs. So I went to “Start” menu, right-clicked “All Programs” to open startup folder, copied Privatewall icon into same so as to at least not forget to use it, and now every time my OS starts/restarts with no such hangs and Privatefirewall working as it should…a pleasant surprise for once.

    There are a very few types of malware Privatewall doesn’t protect against, but most competent AVs do; also, one needs a good antilogger (such as Zemana) as this FW doesn’t faze loggers. For those interested, my Privatefirewall on highest settings itself alone scores 290/330 current Comodo Leak Test…almost twice what my resident Windows firewall scored. Hope this is of use to at least some windows users.

  4. I use Online armor premium for a few years now and i can say i am very happy with its performance together with Kaspersky antivirus ( not the internet security bundle ) together they are a deadly combo to protect my pc’s

    So your solution was to remove Privatefirewall from startup ? How is the situation now ?

    In Feb 2015, I installed PrivateFW 7.0.30.3 (latest-available version, released in Dec 2013) for the first time. But upon reboot & login, I kept getting a black screen with just a mouse pointer.

    Task Manager (CTRL+SHIFT+ESC) indicated that kernel.sys was hogging 25% of the CPU, while the majority of system processes were not even loaded. (The Task Manager listed very few processes, even less than in Safe Mode). Furthermore, there are no 3rd-party software that start up with my system, so it can’t have been conflict with these.

    Repeated reboots resulted in the same black screen immediately after login. The “solution” is to boot into Safe Mode (… apparently PrivateFW does not start up with Windows in Safe Mode, Task Manager listed 0 PrivateFW processes), upon which I performed System Restore. My OS is the same as yours: Win 7 SP1 Home Premium (64-bit).

    Incidentally, Privatefirewall seems quite famous for causing a black screen at start (or login after logout) for many Windows 7/8 users since 2011/12. Some of them are Avast Antivirus users, but I have never installed Avast. In fact, when I installed PrivateFW, my system had no antivirus program because I’d cleanly uninstalled the previous one & rebooted a few times, before installing PrivateFW.

    Until now, PrivateFW;s developer has neither resolved this, nor mentioned this issue at the Support page. Moreover, this “highly recommended” firewall has received hardly any
    updates as of Jun 2012. There were 2 minor updates in 2013, & none since
    then.

    I am keen to try Privatefirewall, but considering the lack of updates & the numerous black-screen complaints(totally left unaddressed by the developer), my reservations are not unjustified. In comparison, I have not encountered similar black-screen problem with Comodo Firewall or ZoneAlarm Firewall.

    Avast Free + PrivateFirewall= black screen at start

    times untill desktop is showed. Sometimes screen is black but you can
    see mouse arrow”
    User B:Same problem here. Don’t have to reboot, just Ctrl-Alt-Del, logout and then login again [to get black screen]”
