Security Tools: Frequently asked questions (FAQ)
Q. What is a firewall?
A. A firewall (or Internet firewall) helps make your computer invisible to online attackers and some malicious software such as viruses, worms, and Trojan horses. A firewall can also help prevent software on your computer from accessing the Internet to accept updates and modification without your permission. Firewalls come in both software and hardware form, but hardware firewalls are intended for use in addition to a software firewall.
It is important to have both a firewall and antivirus software turned on before you connect to the Internet. Security Tools: Frequently asked questions (FAQ)
