Thanks everyone. That is lots of great information. I will get started with ClamAV and all check on other info everyone provided.
To answer a question that someone had asked on the thread, yes I will be using it as an user (and not as root!) and email at times.

For Linux systems antivirus is not as important as it is under windows.
But depending on what you use your system for you may want to run things
like chkrootkit and tripwire.
chkrootkit examines your system looking for indications that it may have
been compromised. Tripwire takes a snapshot of the files on your system
and compares current files to the snapshot. If someone has compromised
your system tripwire will report those changes to you.
Also learn how to use iptables and get your system locked down. Turn
off services that you don't need or use and only open ports up for
things that you do use.
And if you are on cable or DSL put a dedicated firewall between your
cable/DSL modem and your home network. This can be a linux box that has
been hardened and used iptables or if you just want something that works
and is cheap and will require little or no administration once it is
setup get a netgear or linksys cable/DSL router firewall.
The firewall alone will eliminate most vectors used by hackers to break
systems. And if you are running iptables on your system you have a
second layer of defense. Just make sure it is setup correctly.
Things like chkrootkit and tripwire are intrusion detection tools and
will alert you if someone has tampered with your system.
You can also use things like snort that will monitor network traffic
looking for suspicious traffic. This is good for comp! anies to actively
monitor for attacks but may be more than most people need on their
private networks.
If you are supporting windows clients and using a linux box as their
email server you can use clamav and similar type programs to scan for
windows type viruses.
Good luck.
