Linux Viruses and Malware ?

[colinvespa]

From what I understand the biggest advantage of Linux systems is that they are unlikely to be attacked by Viruses and Malware, how much of a threat they really are ?

Are they much of a threat ? I haven't actually seen much in the way of Linux firewalls and anti viruses software.

Hope you can clear that one up and perhaps fill in the gaps for me and for others who are reading this,

Thanks all

Is there any Linux specific anti virus by any chance ?

Thanks I know AVG but not familiar with the others.
