An anti-virus and a firewall protect your computer in different ways.

Anti-virus software:

  • examines software and files as they are written on to or read from your computer's hard drive
  • determines whether or not this software is malicious
  • blocks malicious software (malware) from infecting your computer.

A firewall:

  • filters network traffic to and from your computer or local network
  • prevents hackers from accessing some parts of your computer or local network
  • prevents some viruses from spreading over the network.
