Ok. I got my instalation CD in the mail yesterday. I have a hoard of "pre install" questions. What about a firewall?? Is there one included?? If not, where do I get one?? I have a marvelous data erasure program. I assume that because it was written for Windows XP, it will no longer work in the Linux environment. Is there such a beast in the Ubuntu world?? What about anti virus?? What's available or is that included in the OS??? Same question as for the firewall!!! Give me some answers, Ubuntu users!!
