A alternativa correta é a letra "a) I e II estão corretas". Um firewall é uma barreira de proteção que controla o tráfego de dados entre um computador e a Internet. Ele age como uma defesa do computador ou rede, controlando o acesso ao sistema por meio de regras e filtragem de dados. O firewall não é um tipo de vírus que ataca o sistema do computador e não precisa ser instalado em cada máquina conectada à rede, mas sim em um dispositivo de rede que controla o tráfego de dados.
