firewall, spyware etc software

Im currently running leopard with the built in firewall i was looking for some antivirus, spyware software possibly a different firewall any suggestions as im not sure whats good for macs! Thanks

There are no viruses or spyware for Macs. Hence you don't need any antivirus software.

There's no need for an anti-virus or spyware solution as there currently are no viruses and only a couple of trojans out there that are easily avoided by simply being vigilant when prompted for your password.

If you'd like a firewall that gives you a more granular degree of control over outbound traffic, check into Little Snitch.
