Using an antivirus is important if you want to protect your PC, and sometimes you might want to prevent certain applications from accessing the Internet. To do that, you need to use a firewall, and today we’re going to show you the best two-way firewall for Windows 10.

Here are the best two-way firewall tools for Windows

There are two types of firewall, and a one-way firewall will protect your PC from incoming threats. On the other hand, a two-way firewall will prevent malicious applications that you might have on your PC from connecting to the Internet. As you can see, two-way firewall adds another layer of protection, so it’s a must-have tool if you want to protect your PC.

There are many standalone two-way firewall applications for Windows, but many antivirus applications also have a built-in two-way firewall that can protect your PC. If you want to protect your PC from malware, you might be interested in one of the following applications:
