Installing Linux is trivial nowadays. You just need to download ISO image, burn it on CD/DVD and reboot the machine. But, what if… the computer doesn’t have a CD drive? Well, don’t worry. In such case you can install Linux directly through the net. This is called PXE and in this article you’ll learn how to use it.

One great advantage of using Linux (Ubuntu) is the fact that you don't really have to worry about security and hence viruses. However, this does not mean that you should not use an anti-virus on your Ubuntu machine. Especially when you can get a good anit-virus for free. BitDefender for Unices is one such anti-virus solution for Linux and you can get it for free.

GNU/Linux systems are immune to viruses is anything but myth. Viruses, malware are programs with destructive intentions and can be installed on any machine throgh various means. It becomes extremely easy if an attacker/cracker (not hacker for god's sake, you idiot) gets physical access to the machine. You can install a malicious code on your own computer if you want.

Just because you use Linux, it doesn't mean your computer doesn't have viruses or worms. Virus is a catch-all phrase, and BitDefender's designed to catch them all - from executable viruses, script viruses, macro viruses, to backdoors, trojans, spyware, adware, diallers, and more.

I want to talk about an interesting thought I had in regards to answering the common question of... "why is it free?" I used to reply it is free as in freedom... to which they respond with a pause a blank stare before they either say "really" or change the subject. I have not even touched on the reaction I get when I tell them that I do not need to worry about viruses and spy ware.

"Some of us are perfectly happy just having a system that we no longer have to worry about."

My guess is you are using the best program of all, which is why year after year you are free from spyware: common sense. Firefox is a good browser because it has proven less vulnerable than Internet Explorer. Also, keeping your security settings high is helpful. Regular running of AVG antivirus, Ad-Aware and Ad-watch are helpful, too. The best protection from viruses and Spyware is using the noggin. Think before you click.

A friend of mine was telling me how she went to buy a new computer, asked to have Linux on it, and was told “Linux is not good for you at home” and that she shouldn’t worry, they’ll just install her Windows XP and all the things she really needs, “for free”.

Imagine a different way of computer life. For 80% of your computer-using time, you carry a usb key as your notebook computer You come to a foreign place and are allowed to use an unfamiliar computer. The computer may work perfectly or it may have been rendered non-bootable by a virus. It may be a powerful one or it may be an inexpensive netbook. It may speak Zulu or Tamil.
