There is no substitute for a good up to date anti virus program. A firewall can prevent many intrusions and many out going connectios, but can do nothing for an infection, and some types of virus can disable a firewall. Good anti virus software is an absolute must have.

what protections do you have?? are you having any current infection problems??

more info about your computer(s) and/or network

A firewall is very important to have, but like 2k_dummy says, you absolutely must have anti-virus (as well as anti-spyware) protection programs.  Just one program isn't enough.
