Virus

A virus is a computer program that is made to harm our computer data, files, and other programs. Viruses can spread computers to computer and they can replicate themselves.

A firewall is a network security device that monitors incoming and outgoing network traffic. It establishes a barrier between our internal network and incoming traffic from external sources (such as the internet) to block malicious traffic like viruses and hackers. A firewall can be either hardware and software.
