Same with @Vuluts and @Lucifer . I usually use iptables for my firewall in linux . But you can install freeware antivirus (googled it )

I think Linux comes in with a built in firewall? I think its called iptables or something

If you're searching a good iptables preset, I can give you one I used on my fablab's server! Let me know in PM.

Yea its iptables but you need to configure all rules to make it work perfectly.

Which firewall is best for Linux ? Does anyone offer free firewall for Linux ? Have you guys tried it ? How was the experience ?

if you need firewall to protect agaisnt virueses i dont really think you need it because linux itself have almost no virueses because no one develop virus for it . the virueses developer thinks : why i need to make virueses for linux? the user base isnt big and also most linux user are enthusiast and they are probably know about removing virus or preventing to get virueses
