What is the Ubuntu “built in virus protection”?


Anti-virus software is a program or set of programs that are designed to prevent, search for, detect, and remove software viruses, and other malicious software like worms, trojans, adware, and more.

These tools are critical for users to have installed and up-to-date because a computer without anti-virus software installed will be infected within minutes of connecting to the internet. The bombardment is constant, with anti-virus companies update their detection tools constantly to deal with the more than 60,000 new pieces of malware created daily.

There are several different companies that build and offer anti-virus software and what each offers can vary but all perform some basic functions:

Scan specific files or directories for any malware or known malicious patterns Allow you to schedule scans to automatically run for you Allow you to initiate a scan of a specific file or of your computer, or of a CD or flash drive at any time. Remove any malicious code detected...

For most new users, the fact that there are more than 8 official "editions" of one Ubuntu operating system is hard to understand. It's particularly similar with Microsoft having some editions for Windows XP, and the users would ask "what are the differences?". This article mentions the differences of nine Ubuntu official "editions" (called


) based on the

desktop interface


specific purpose


file manager

, and

LTS duration

. This article also provides more information such as Wikipedia entries and other important resources to make it simpler to understand. I write this article in January 2017 and the number of flavors can be increased or decreased later.

C: What drove you to use Ubuntu as a server if you didn't like its stock desktop? Ubuntu is a desktop-driven distribution. If you aren't passionately into their GUI.... why not run CentOS for you server?

I'm flying absolutely blind, total Linux n00b. I'm following a set of installation instructions, step by step, for installing the Ubuntu server and SA and a bunch of support apps. http://www200.pair.com/mecham/spam/spamfilter2.html

I did post a couple of days ago asking for clarification of some of the instructions and a few people said they'd used them also and they were great.

So, not knowing jack about Linux, I'm gathering info and obviously using it to learn something new. I did not know U server had a desktop, I know U "desktop", of course, does b/c I also downloaded and installed a copy of that first.

Relative to B:, I'm guessing having a GUI file explorer window would be handy for getting a handle on...

Part of the appeal of Ubuntu is its six-month release cycle. Every six months a new version of the free operating system is released into the wild, complete with updates for all of your favorite software. This is great, but can be a trifle disappointing from time to time. For example, if a new version of your favorite software comes out you may have to wait until the next version of Ubuntu comes out to try it.

The solution to this is the PPA. This is a repository, provided by Canonical (the company behind Ubuntu), that allows developers and enthusiasts to offer up-to-date versions of software to all Ubuntu users. Originally PPAs were limited to programmers and testers, but Canonical opened PPAs to everyone in late 2007.

I constantly mention PPAs in my Ubuntu articles because for the newest software, installing a PPA is the simplest way to get everything working. But what is a PPA and why would you want to use one?

Ubuntu 12.04 LTS (Long Term Support), aka Precise Pangolin, will be released towards the end of this month. Like most distribution releases, it will come with its share of new features, enhancements and bugfixes.

You will find one of those new features in System Settings, the hub for most graphical administrative tools in Ubuntu and GNOME 3 desktops in general. The tool or application is called Privacy. What it does is not new per se, but new in the manner it executes them.

Since Privacy is not available on current and earlier editions of Ubuntu, you need to be running a pre-release edition of Ubuntu 12.04 to see first hand what is being discussed in this article. If you have such a system, you will find Privacy in the System section of System Settings, that is, in the lower section.

This is Privacy’s main view. It has four tabs. What it does, is record application activities on your computer. And there is nothing new about that. On a KDE desktop,...

The blog posts have slowed down a bit lately because I’ve been heads down on a security project at work. I’m working with people in the OpenStack community to create a new Ansible role called openstack-ansible-security. The role aims to improve host security by using hardening standards to improve the configuration of various parts of the operating system.

This means applying security hardening to Ubuntu 14.04 systems since that’s the only host operating system supported by openstack-ansible at the moment. I have plenty of experience with securing Red Hat-based systems like Red Hat Enteprise Linux, CentOS and Fedora; but Ubuntu is new territory entirely. The rest of this post is full of lessons learned along the way.

Searching for hardening standards

Finding a complete hardening standard for Ubuntu 14.04 is challenging. The Center for Internet Security offers Ubuntu security benchmarks with two big caveats:

There are very few controls to apply (relative to...

Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit.

Ubuntu will always be free of charge, and there is no extra fee for the “enterprise edition”, we make our very best work available to everyone on the same Free terms.

Ubuntu includes the very best in translations and accessibility infrastructure that the Free Software community has to offer, to make Ubuntu usable by as many people as possible.

Ubuntu is shipped in stable and regular release cycles; a new release will be shipped every six months. You can use the current stable release or the current...

Get an Ubuntu LiveCD Go to ubuntu.com and click the button for "Get Ubuntu". The fastest way to get a CD is to download a CD image (it will be a .iso file), and burn it to a CD. The file will be almost 700Mb, which can take 4-8 hours on a broadband connection. Note that the contents of the .iso file must be burned on a disc, not the .iso file itself. To do this, you will need a CD burning application such as InfraRecorder (infrarecorder.org), which will burn the data in the .iso to disc. Boot from the CD It may be a wise idea to backup important files you don't want to lose at this point. If you intend to completely overwrite all your files and previous operating system, or if this is a new computer, you don't need to. Boot your computer with the CD in the drive. You may have to change settings in your BIOS to make the computer boot from the CD. At the Ubuntu menu, select either "Try Ubuntu Without any Change" or "Install Ubuntu". If you "Try Ubuntu", you will be taken...

There's a kind of war going on and we're all caught in the middle. In that war, the two superpowers are Microsoft and Apple. The battlefield is the operating system. Numerous ad campaigns give the impression that these are the only two choices out there for anyone looking to buy a computer. But there's a small group of rebels out there who know better. Their OS of choice is Linux and they back a very different philosophy than the one followed by the big companies.

Linux is an open-source operating system. To really understand what that means, we need to define some terms. An operating system is a layer of software on a computer that acts as a foundation for computer programs. It's the OS's job to monitor computer resources and allocate those resources to programs that need them. When you execute a program, the OS acts like a supervisor and makes sure the program has the processing power, memory and any other resources it might need to function. Operating systems make it easy...

“A Computer Virus is a malicious software program “Malware” that can infect a computer by modifying or deleting data files, boot sector of a hard disk drive or causes a software program to work in an unexpected manner”.

A computer virus resides on a host computer and can replicate itself when executed. Virus can steal user data, delete or modify files & documents, records keystrokes & web sessions of a user. It can also steal or damage hard disk space, it can slowdown CPU processing.

Definition of Computer Virus

“A computer virus is a program that may disturb the normal working of a computer system”. Virus attaches itself to files stored on floppy disks, USBs, email attachments and hard disks. A file containing a virus is called infected file. If this file is copied to a computer, virus is also copied to the computer.

Activation of Virus

When the computer virus starts working, it is called the activation of virus. A virus normally runs...

In a word, "no."

Any computer that is attached to a network is not immune to viruses. But, as with everything else, it's relative. If you compare the vulnerability of Linux to Windows, you can understand why so many say Linux is immune. But before we get into any myth busting, let's examine just what a computer virus is.

According to Wikipedia, a virus is a computer program that can copy itself and infect a computer. That's a pretty broad description. Most people would consider a more specific definition. That same Wiki page continues on to say The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, adware and spyware programs that do not have the reproductive ability. Now we're talking. So with the two definitions combined, you could say a computer virus is any type of malicious code or software that can either infect a computer and replicate/distribute itself or a piece of malicious code or software that can be...
