Securing your home PC from black hat "hackers"

There are three basic items that will stop almost all black hat "hacker" attacks on your home computer; Firewall, Up to Date Anti-virus and System Updates.

Firewall - Your computer should never be connected directly to the internet without some sort of firewall protecting it. Most broadband router/hubs act as a firewall as do most external DSL modems. How do I know if my internet router/hub/modem is a firewall too?

Up to date Anti-virus - Firewalls don't protect you from everything. E-mail and web browsing are the two most common activities that firewalls

System updates - Most attacks exploit an already known vulnerability that already has a fix released by your OS vendor.

How do I know if my internet router/hub/modem is a firewall too?
If your computer's IP address is in any of the following ranges, you are behind a firewall:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
169.254.0.0 - 169.254.255.255
You can find your computer's IP address by opening a command window and running the command for your operating system:
Windows 95/98/ME: winipcfg
Windows NT/2000/XP: ipconfig
Linux/UNIX: ifconfig
