Does linux/ubuntu need anti-virus, antispyware, and a firewall?

I have avast for Linux on there (so I basically already put anti-virus on there anyway) but is it necessary to take all the precautions I would normally take with Windows? Why/why not?

    There are firewalls for linux, well basically you just close all ports and only leave the ones you need open open. but i only rememeber it was something with iptables.
    And since virusses/spyware that actually works on linux is very very rare and uncommon you dont need a program for that.
    Entering commands with your eyes shut is far more dangerous that living without a virus scanner.

    It is not necessary, but it doesn’t hurt either.

    Most Linux users only download software from the repositories that are already listed on their system by default, or trustworthy ones that they add; those repositories are checked to ensure that the software in them has no malware, because of the way Linux users get their software, it is very unlikely that they will get any form of malware even as popularity grows.

    To modify, add, or delete anything from the system, you will either need to login as root or use sudo, both of which require you to enter your password. This basically eliminates the threat of catching malware by simply surfing random websites, although I highly suggest clearing your cache and flash cookies after words.

    Having a Firewall is always a good idea, regardless of the operating system.

    If you prefer to manually add rules to iptables (basically your firewall), then here is an Ubuntu documentation to help you get started.

    If you want a GUI to manage iptables easily, then I suggest you download Firestarter.
