A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. On the other hand, an antivirus is a software program designed to detect, prevent, and remove malicious software, such as viruses, worms, and Trojan horses, from a computer system. While a firewall focuses on controlling network traffic, an antivirus focuses on identifying and eliminating specific types of malware that may have already infiltrated the system. In summary, a firewall is a network security tool, while an antivirus is a software tool designed to protect individual devices from malware. **
