The best overall firewall: Fortinet. The best simple firewall: Ubiquiti EdgeRouter. The best enterprise firewall: Cisco NGFW. The best free software firewall: OPNSense.
The free version does not contain a firewall but you can use your windows firewall with it. You have to buy the full version if you want a firewall with the software. I found that Norton 360 is the best for me.
The best free firewall is the one built on to most computers. Better firewalls cost a lot of money. Software that claim to be free and better than built-in firewalls are usually spam or malware.
PCtools firewall is OK I mean it does not pass Shields UP test which is the general firewall test site... If you are really looking for free best firewall then Zonealarm Basic firewall or Comodo firewall Pro is best... Install any one and will provide you great protection from outside attack
In my opinion AVG Antivirus, i am not sure if they free version comes with the firewall or not, but either way its is a great antivirus and firewall combination.
When it comes to free firewall, Comodo is the best which offers a very good firewall protection. Here is the list of companies offering free firewall software. 1. Comodo - personalfirewall. 2. Emsisoft Online Armor Free 3. Agnitum Outpost Free Internet Firewall 4. Tinywall - Lightweight Firewall

There are many different brands of free firewall software. Some of the more popular brands are Cisco, Comodo, Online Armor, and Zone Alarm. All of these are free for download on the webpages of the same names.
I have a very effective firewall on my computer that I downloaded for free from Sygate. It blocks any harmful computer viruses from coming in.
I personally recommend Avast and Microsoft Defender. However I also use the windows firewall and the firewall on my router for added security The popular website cnet.com lists AVG Anti-Virus Free Edition as one of the best anti-virus free software packages available.
The best firewall software solely depends on a persons needs and price range. A good firewall software to use is Norton Antivirus, due to it being reasonably priced, offering free trials, and overall a good protector against computer viruses.
