Are you using your linux box as a file or mail server for MSWin boxes? If so, there are several available to ride herd to protect winboxes downstream of your servers. If you are just trying to protect your personal Linux system, a firewall should be enough since Windows viruses/malware can't "live" in a Linux environment.
On a semi-related vein, if you want a web-content filter to keep surfing pretty clean for your kids/organization, I can recommend dansguardian.
