Viruses, spam and phishing FAQ
Why do I need both anti-virus software and a firewall?
A firewall examines each data packet that enters or leaves your computer. It prevents hackers from accessing your computer, passwords, financial information, and any other type of information stored on your computer. It also blocks other Internet threats like hacking, worms and Trojan horses that cannot be detected by anti-virus software.
Firewalls don’t necessarily protect your computer from all types of viruses, which is why it is recommended to install both anti-virus software and a firewall to maximize your protection.
