Is there a real big need for having an anti-virus on linux?
if so what are some good ones to use?
There are no 'viruses' (in the MS-Windows sense) for Linux *in the wild*. There are rootkits and from time-to-time exploits in various network services. If you keep things up-to-date and use a properly configured firewall, etc. this is generally not a problem.
If you are running a file or mail server for MS-Windows clients, there are scanners that check for *MS-Windows* viruses.
