I've seen quite a few threads on this forum that say that Ubuntu and Linux in general are so safe that a firewall and antivirus software are not needed.
When I was looking at the features of Ubuntu 12.10 desktop, it says "You can surf in safety with Ubuntu — confident that your files and data will stay protected — thanks to the built-in firewall and virus protection."
What I'm wondering is:
1. Why would Canonical add these pieces of software if Ubuntu is so safe, has something changed?
2. Would anyone know what is the name of the firewall and antivirus software that Ubuntu has added in 12.10?
