And there are people just waiting to break into your computer to access and manipulate your files. Anti-virus software and spyware detectors are not sufficient to ensure your protection from attack. Firewalls were developed to help protect computers from these break-ins. Windows XP comes with a built in firewall. If you have Windows XP, do you know if your firewall is enabled? Is it the most effective one for your needs? Do you even need one?
