I am using Ubuntu 20.04 and want to know if I need to install firewall/antivirus software. The "Similar questions" seem to all be outdated.

Malware/viruses targeting Linux are pretty rare, to the point that you usually don't need to install an antivirus software. If you really need that extra layer of assurance, you can use ClamAV. sudo apt install clamav clamtk
should do the trick, and give you a nice GUI for it (ClamTk).
sudo ufw enable
to enable a basic firewall setup.
