Antivirus for Linux 7.3

[CCI-ICC Administrator]

Hi   My name is Michael, I am the System Administrator for CCI Pty. Ltd.   We are currently installing antivirus software on our network. I have noticed that Linux does not support "Symantec, Norton Antivirus", which is the standard for all our other "Windows" based servers (except for our mail server). Can you please advice us, which Antivirus software is best suited for Linux 7.3?   Kind Regards.   Michael.
