Should I enable firewall Linux Mint?

A firewall is always desirable but you don’t absolutely need one like you do in windoze. Linux doesn’t keep ports open like windows does. If you’re running a server or perhaps doing a lot of torrents then you should have one. Run it in menu>settings>firewall configuration.

Does Linux need an antivirus program?

Anti-virus software does exist for Linux, but you probably don’t need to use it. Viruses that affect Linux are still very rare. Some argue that this is because Linux is not as widely used as other operating systems, so no one writes viruses for it.
