Hi Windows firewall is not that bad as some might think. Perhaps it's even powerful. Just wanna ask how do you make quite secure system.... 1: Updated Windows Defender (I'm not gonna install anything, except maybe Firefox and Steam. No odd exe files. Patches to OS, also) 2. Windows Firewall. (Now this is the main part! I have already blocked any inbound connections. Any outbound are allowed. Remote control (from another computer) I disabled with usual GUI.) I also created standard user (In Linux it's non-root user). What else can be done to firewall, and perhaps other things? Any services running in background that are listening for example? Not wanting to spend money for antivirus any more, not even free like Malwarebytes.
