Of course all PCs have Windows Firewall, which is quite good at blocking inbound connection attempts (Not quite as good if you're still running XP). True, Windows Firewall doesn't alert you if a program on your PC tries to establish an outbound connection (as nearly all programs do, if only to check for updates). But if there is malware on your PC trying to "phone home," then AVG antivirus protection has already failed you. Here's an article that I think is good: http://www.howtogeek.com/172349/why-you-dont-need-an-outbound-firewall-on-your-laptop-or-desktop-pc/
AVG Internet Security costs about $55. There are plenty of posts at this Community from users who have trouble with the firewall. Personally, I would never buy it. Here's an impartial review:

"Saving the world from bad software"
Donna, Firewall blocks hackers attempting to access the private data stored on your PC. Stops malware taking over your computer or from harming other peoples. Works on wired and wireless networks.
Firewall is a system that enforces an access control policy between two or more networks by blocking/ permitting traffic. The Firewall contains a set of rules that protect the internal network from attacks originating outside (typically from the Internet) and controls all communication on every single network port. The communication is evaluated according to the defined rules, and then either allowed or forbidden. If the Firewall recognizes any intrusion attempts, it “blocks” the attempt and does not allow the intruder access to the computer. Firewall is configured to allow or deny internal/external communication (both ways, in and out) through defined ports, and for defined software applications. For example, the firewall could be configured to only permit web data to flow in and out using Microsoft Explorer. Any attempt to transmit web data by any other browser would be blocked. It protects your personally-identifiable information from being sent from your computer without your permission. It controls how your computer exchanges data with other computers on the Internet or local network. Within an organization, Firewall also protects individual computers from attacks initiated by internal users on other computers in the network.
In AVG Internet Security 2015, the Firewall controls all traffic on every network port of your computer. Based on the defined rules, Firewall evaluates applications that are either running on your computer (and want to connect to the Internet/local network), or applications that approach your computer from outside trying to connect to your PC. For each of these applications the Firewall then either allows or forbids the communication on the network ports. By default, if the application is unknown (i.e. has no defined Firewall rules), the Firewall will ask you if you wish to allow or block the communication attempt.
