There are alot of programs that run in the background of your computer and some of those programs open up ports that can allow a hacker into your computer. By shutting down these programs that are most of the time unnecessary we can eliminate the amount of ports we have open on a computer.

You can also purchase a third party firewall program that will help block these ports. There are many third party companies that provide excellent firewall programs. Firewall Gold
Have a router between you and the internet
Some ISP (internet service providers) such as cable allow you to plug into their modem and it gives your computer a public IP address. By installing a router between your ISP modem and your computer you can not only share your internet connection but you are also protecting yourself by not publishing your IP address to the internet.
A simple router is pretty inexpensive depending on the features that you get with it like wireless. Places like Best Buy and Global Computers have these routers.
