Was wondering what are the best anti-malware programs for ubuntu... and firewall?

For instance, with windows i use, CCleaner, Malware-Bytes, Avast, KVRT, etc

For firewall just use iptables, don't need anything else. For av, most the normal Windows solutions have Linux versions. I've been happy with clam in past. But you don't really need it the way you do in Windows...the best thing you can do is just too keep everything up to date.
