A personal firewall will protect your personal computer against network intrusion but it will not protect your personal computer against virus. You will need antivirus software.
Firewall is only for those with in depth knowledge on their computer and on networking. It is not intent for anyone. We do not provide any support on Firewall issue.
A number of companies make firewall products. Features include logging and reporting, automatic alarms at given thresholds of attack, and a graphical user interface for controlling the firewall. It is up to you to choose which firewall software you want to use but you must be familiar to that particular firewall software. Having an incorrect setting on your firewall will disable your ability to browse the Internet and check your email.
