Do you require a firewall on Windows 7?
The default security measures work well for most situations. A secure home network is ideal, though threats remain, so a hardware firewall should follow a software one. Those who claim otherwise are likely misunderstanding the capabilities of Windows Firewall. The main risk arises when accepting incoming connections, which can lead to compromise. I rely on a custom firewall, but I’d prefer the built-in one. I’ve heard from a penetration tester at a U.S. military base that Windows Firewall is among the strongest available. For stronger protection, consider a Fortinet solution or similar. Since I’m experienced and aware of serious weaknesses, it’s wise to disable IPv6 on your network adapter. Such actions can stop spam attacks quickly and render devices unusable if not properly configured. Turn off file sharing unless necessary, as it consumes bandwidth. Block all incoming traffic unless you specifically require certain ports like 80 or 443, which should stay open for normal access. For further guidance, feel free to reach out.
You're joking... Right? Most people these days have a router of some kind be it a standalone router or one built into their modem and they almost always have a firewall component. The days of connecting the family PC directly to the modem and needing a software firewall are mostly gone. The only thing you gain by running a software firewall that your router's firewall likely isn't doing is restrictions on outbound traffic that could in theory stop something shady from "calling home." Provided you're running some sort of Anti-virus/Anti-malware protection chances are anything that needs to talk outbound to the internet is something that needs to such as IM clients, games, and so on. Unless you're the kind of person prone to installing viruses, are completely paranoid, and/or desire the ability to control the communication of even legitimate software not considered a threat by your AV there's no real reason to even leave the built-in firewall running. If you're going to leave it running you can probably set the inbound to Allow as your router is already doing it and you're just adding a layer of complexity. There is absolutely zero need for a third-party software firewall above and beyond the built-in Windows Firewall however.
My Windows desktop looked okay at first, but scanning it revealed 20 viruses despite the Windows Firewall being active. That’s not ideal.
The longer you own your PC, the better you understand its performance limits and can confidently detect issues like resource theft. I haven’t used antivirus software for years; I rely on the Windows Firewall for protection. The system has remained stable over time, performing well without problems—just as I expect. I’m familiar with the typical startup processes of common executables and overall machine behavior. The firewall is the most reliable part of it.
I'm not evaluating, just sharing observations. As you gain experience, you'll understand better what actions are appropriate and which aren't online.
