I am seeking Firewall Software that is better (in terms of protection) than Windows 10 built-in Firewall, very easy on system resources, and also free. So far I came across Free Firewall and Windows 10 Firewall Control, but neither do I know much about them nor do I know much about Firewalls or PC Security or Networking, aside from Basic Networking. I just know I prefer to keep very few services in the background when I game. I apply a LOT of tweaks and literally have only the absolutely necessary services, driver-services, and tasks (only 2 out of 150-something Windows 10 background system tasks are enabled!) because I just need this PC for Gaming, Home-Theater, basic Internet network (directly hooked to cable router/modem with DMZ enabled for my MAC address), and I don't even plan to update it, unless its a full clean OS re-install. My tweaking also includes turning off some security holes in DCOM RPC, (port 135) + all tweaks from Windows Worms Doors Cleaner, disabling NetBIOS service, and turning off LMHOSTS lookup. Ethernet Status actually says I have no connection at all, yet somehow I am posting this! When it comes to browsing I stick to Chrome with uBlock Origin + uBlock Origin Extra + ScriptSafe + HTTPS (if possible) + a few hundred blocking entries in Hosts. I don't visit sketchy websites, I haven't had any spyware/malware or viruses on any of my PC's since 2009, and although I keep several anti-spyware/virus software like AdwCleaner, Hitman Pro, and Malware Bytes - I never have them running or even install them because my PC is always clean like that. Given that: - So much is disabled on my PC (including Windows Firewall Service) - DMZ enabled in router (but router Firewall is ENABLED) - My Internet safety habits / setup ...is there a high chance of me being hacked or attacked, assuming I won't piss anyone off? Should I even bother with that light firewall I am seeking (for "just-in-case" scenario)?
