First, are you sure you are running 10.6.8 on a G4??? The PPC machines will only use up to 10.5.8.
If you want anti-virus software, one of the favorites of the users on here is ClamXAV...a free download, see the app store. Avoid things like Norton AV as it is a nightmare for most users.

My Power Mac G4 (OSX 10.6.8) has possible been infected with a virus.
How do you know?

I don't know for sure. I'd like to check - at the recommendation of CNET I downloaded and ran a quick check for the Flashback virus but it said I was OK.
My wife's e-mail account was hacked so she changed her password so it wouldn't send bogus messages to everyone on her address list.
The other morning I kept getting kicked off my office e-mail I access via Citrix. With both these problems happening at the same time I thought maybe it would be a good idea to check for viruses and put some protection in place. I realize Macs aren't as vulnerable right now, but do you think it would be a good idea to prepare for the worst?

Apple has patches out for various Mac OS X versions for Flashback, run Software Update to make sure you are updated on the security patches.
Email problems under Cirtix are probably a different issue, could be issues with your certificates if you are using any or issues at the server end if it is running XenApp, I have issues on that end on occasion.
Again, if you feel you really must have an anti-virus program, get ClamXAV rather than some of the commercial, for-sale programs on the market. ClamXAV is popular with users on here and does a good job without being too intrusive to your normal operating.

I'd give it a 98% chance that your mail service provider and NOT your iMac are the problem. Lots of mail services have been hit lately and their clients address books have been compromised.

You will find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful:

Forgot to reference that Tip after being severly chastised and beaten about the head and shoulders for saying it was by Klaus instead of Klaus1

Besides ClamXav, you might also consider Sophos Anti-Virus for Mac Home Edition. It is also free (for non-commercial use) & shares some features (most importantly the same malware definition database) with that company's commercial AV products.
I have been using it for over a year. It has never caused any problems or slowed down my Macs in any noticeable way. The interface is very polished & Mac-like, easy to use & preconfigured with the options enabled that give you maximum protection & control over detected threats.
Compared to ClamXav, its database seems more complete & more quickly updated when new malware variants appear, & its "on access" scanner seems (to me anyway) to be a better approach to 'always on' scanning than ClamXav's Sentry (available only in the download from www.clamxav.com, not in the Mac App Store version).
Also, ClamXav can have problems scanning an entire hard drive (see http://www.clamxav.com/faq.php#Q7). You don't need to do this often: if you have some 'on access' type scanner running you really only need to scan the entire drive once to make sure nothing harmful was installed before you started using the software. Sophos does this with its configurable "on demand" scanner. It takes a very long time to complete, especially if you set it to check inside compressed files (zips, dmg's, etc.), but it doesn't hang like ClamXav might.
