<human>:  Can a firewall protect against a short circuit?
<bot>: No, a firewall can not protect against a short circuit. A firewall is a computer program that protects unwanted attacks from penetrating a computer. Firewalls are installed on computers and conduct routine background maintenance. A short circuit is an electrical failure resulting from wires unable to conduct currents. Short circuits, especially during updates can lead to the dreaded Windows Blue Screen of Death.
