  1. This makes no sense to me. Firewalls were designed to keep bad stuff OFF your computer. The programs ON your computer, generally, you trust and if you don’t they are generally removable. It’s viruses, spam bars and programs that load themselves into your registry you want to BLOCK. Try that.

  2. Actually windows firewall is not a bad solution, and it is very quick and (free!). Windows also provides a virus protection tool called microsoft security essentials, which surprisingly works just as good if not better (if you like something lightweight) then the expensive ones you can buy like norton, mcafee etc.

    Good article, thanks for the info : )

  3. Just for anyone who see’s this post from googling windows firewall.

    Your question was answered. But anything Microsoft is absolute garbage. They bought Giant and call it windows defender, which is the worst malware protection there is.

    If a little old lady surfs the news then Microsuck security essentials is good. If you go places that aren’t good, then you get Bit Defender, Avast, Avira, and a real firewall like Outpost Firewall.

    If it was so good I would be getting paid to clean or reinstall windows from infected PC’s that only run windows protection. Never had to work on a PC with outpost or one of the top ten antivirus.

    When I use to test Antivirus, defender was in the 30-40 list, where Bit Defender, Avast, Avira, F-secure, Eset, Kaspersky, are in the top 10.

    Most times people let malware in, not that a port was hacked. There is way to much to explain about your software using the net which is most of the problem for a firewall.

    Remember one thing, if microsuck was so good, they wouldn’t have to post thousands of security fixes. There still posting fixes for security flaws in win 8 and 8.1. Which they bragged on how secure it was, LOL

    Windows firewall is ok for most single use, it’s when you run networks and are getting port checks from China, Germany and other places everyday, a 100 times a day, you want something better.

    Avast, Avira have a free version.

  4. Did you hear the latest news: “Antivirus products are doomed to failure” and are catching less than half of cyberattacks. So, Avast, Avira, Norton or Kaspersky cannot prevent you from getting malware. You, probably, already have it. And any non-malware application have bugs that can accidentally expose your private info to bad guys. The best chance of catching malware and bugware is not with antivirus, but with good application firewall.

  5. There is no link to windows firewall using the instructions supplied. I pushed the windows button which brought up the charm/metro menu and brought up the side panel, clicked settings but where is the option to go into windows firewall? It was not there. I had to right-click on the desktop, select personalize, go into control panel home, click system & security and go into windows firewall. Still managed to find it and block it though it took me a bit of searching and cursing but that part of the instructions must be incorrect, out of date or something! X-(
