Firewall and up-to-date AntiVirus.

Most folks have no need for FTP and other TCP ports being open, shut them down.

CABLE USERS - Many Broadband companies will sell you a cable modem (SurfBoard is common) and you will be able to get on the Internet. However I highly suggest you purchase a Cable/DSL router and put it in between your Cable Modem and PCs. A Router with a 4 port switch (for 4 PCs) can cost as little as $50.00 and the control and protection it will give you is priceless.

These Routers will have a easy to use Web Interface and a manual for setup. The Firewall functions can usually be set to default High Level Security to block all uninitiated inbound TCP ports.

I believe this is likely talking about NAT. Helpful, but not the same as a firewall - though manufacturers sometimes don't like to point out the distinction.
