You don't need an antivirus for Linux. Scanners are available but these merely hunt for Windows viruses to prevent you passing them on to other Windows users. Linux ships with iptables that does packet filtering, network address translation (NAT), and port address translation (PAT). Additionally, some distributions include an enhancement for this such as Shorewall, UFW, Firestarter etc., although mostly these will require enabling and configuring. I can't speak for the others but Korora has a very strong firewall which achieves full stealth with GRC for what it's worth. Korora also employs SELinux. Other distros might use AppArmor instead.
