Get a hardware or software firewall
We highly recommend all computer users have a firewall solution. There are two ways a firewall can protect your computer and network.
Hardware firewall - A hardware firewall is a hardware device that is connected to your network. Often many home users who have a home network use their network router as a firewall solution.
Software firewall - A software firewall is a software program that you install on your computer that helps protect that computer from unauthorized incoming and outgoing data. Below is a listing of a few of the more widely used software firewall programs.
