Antivirus and Firewall

Will I need an additional antivirus and firewall? Or does Linux cover these bases. I think I heard somewhere that Linux had far less security flaws than microsoft, but you can never be too careful.

there is alread a built in firewall into your computer, it's called iptables, you will have to set it up though, it's far more comprehensive than the firewall with windows, there are anti virus programs for Linux, ClamAV is one of them.

what are you useing you Linux Box for? if it's just for basic use, internet, e-mail, word proccessing then i've found there not to really be a need for anti virus, but you should setup your firewall incase someone gains access to machine

I honestly think that "anti-virus" software is mostly Snake Oil. It's a highly popularized but rather-ineffective "patch" for a problem that is never really honestly described to the end-user.

In my humble opinion, the problem is not that "rogue software can arrive on your computer and be executed." The problem is that such software, when it arrives, when it executes, succeeds. This is totally preventable.

I don't believe that you can realistically stop the rogue-software problem by trying to keep it from arriving. There are simply too many ways that this could happen. Ditto trying to keep it from executing. The way to stop it is ... keep it from succeeding. And you do that with privileges.

Most Windows systems ship where the one and only user is an Administrator .. and has no password. Anything that an Administrator .. or a rogue executing in his name .. asks to do, will be done. Which is why viruses and rogues succeed.

Make sure that you use your computer, on a daily basis, as a completely non-privileged, ordinary-Joe, user. Have a separate, unrelated account for system maintenance .. an account that is not root. If you wear many hats in your company .. salesman, CEO, accountant, geek .. have separate accounts for each role that you play, with different passwords. No other account should have login privileges.

This is what will keep your system secure. I worry, frankly, about "anti-virus" programs because it stands to reason that they, to do their jobs, must be "all powerful." Which makes them .. a vulnerability. And, in my humble, an unnecessary one.

For Linux, keeping up on your security updates and running the firewall is good practice. I like the "Firestarter" GUI front end but others have been mentioned.
What is a GUI front end? The Linux kernel has a built in firewall. You can configure it manually or use a "front end" program.
Using an anti-virus is really more to be sure you don't pass a virus infected file to your Windows using friends.
There are other Linux security tools that can be very useful.
