I know there are one or two desktop firewall programs available in the software centre of ubuntu 10.10, but are there any antivirus programs available for ubuntu? Can ubuntu even get viruses? How secure is your desktop enviroment? Can malicious users easily access an ubuntu machine if it is connected to the internet?
Thank you :D

Ubuntu is relatively secure, simply because there aren't a lot of people out there trying to exploit Ubuntu.
I'm sure you have heard the whole, "OSX doesn't get viruses," though not entirely true, there is a reason for that. It's because OSX isn't, "top dog." By that I mean OSX isn't the the most widely used OS on the market, which means, for the most part, not a ton of people out there are trying to exploit it, simply because there isn't much to gain from doing so.
Same goes with Ubuntu. Not a ton to gain exploiting an OS that so few people use. I use it and I love it. And to this date, with smart browsing and avoiding malicious sites (porn for the most part) I have yet to have a problem with Ubuntu.

There are anti-virus applications for Linux. You have ClamAV, which is open source, you have Avast, although its Linux version is lacking, and Nod32 which you have to pay for, but it is awesome on both Windows and Linux.
As far as security in Ubuntu, well its based on GNU/Linux, so you can point to its security based on two things. THe most popular reason people claim is "Security based on Obscurity", that may be true for the desktop applications, but doesn't apply entirely to the server-side or the Kernel.
Linux being open source, and the kernel managed by The Linux Foundation - you have to take note that when an exploit is found, it is normally reported and patched very quickly. The same goes for many of the server-side applications, as while the "Security By Obscurity" may be true on the Desktop side, its not so much on the Kernel or the Server-side, as most of the worlds most important web servers run on some form of GNU/Linux. So security is one of the top priorities.
Another aspect to Linux security, and you get this both from a CLI and a GUI, is having only one account be truly privileged, root, and for any administrative task to be done you have to do it via logging into root, or by running commands through root via Su or Sudo. Su requires you to have the root password, and sudo requires the user to be on a sudo user list and they only have to know their own password. So for the system to do ANY serious damage, you have to give it a password. :P

There are some virus out in the Linux/Unix community. But not as popular as windows and Mac OSX. But readily know but haven't seen any in the longest time in linux. But still there is an antivirus available from the software center in Ubuntu. Just a matter of installing it to your computer there.

Any system is only as secure as you make it.Start with a secure password. If your password is '123456', make a new one. At the very least you want to install and run chkrootkit and rkhunter. You'll also want to look through startup services for ones you don't use.
