Antivirus software and a firewall serve different purposes in computer security. Antivirus software is designed to detect, prevent, and remove malware from a computer. It scans files and programs to identify and neutralize malicious code, such as viruses, worms, and Trojans. In contrast, a firewall acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. It controls incoming and outgoing network traffic based on predetermined security rules, blocking unauthorized access and protecting the network from external threats.
The difference between a firewall and antivirus software lies in their primary functions and areas of protection. Antivirus software focuses on identifying and eliminating malware that has already infiltrated a system, offering real-time protection and scanning capabilities to prevent infection. A firewall, on the other hand, is a network security device or software that monitors and controls network traffic. It prevents unauthorized access to or from a private network, acting as a gatekeeper that allows or denies traffic based on security policies.
The difference between a firewall and antivirus software is based on their core functions and protection mechanisms. Antivirus software is primarily concerned with detecting and removing malicious software from a computer system, providing real-time protection against malware infections. A firewall, however, is designed to protect the network by controlling the flow of data between the internal network and external sources, preventing unauthorized access and potential attacks from outside the network. Essentially, antivirus protects the system from internal threats, while a firewall guards against external threats.
