It's geek-popular belief that Linux does not need antivirus, I disagree. Although there are a couple of viruses or Trojan horses that directly affect Linux, it is very difficult to be infected areas in which the user communities do not have script. The purpose of installing an antivirus on Linux is to protect the rest of the network, either through a shared directory in Samba or download from the internet via a proxy.

In this tutorial we will see how to install and configure Dazuko on Ubuntu Linux. Also activate AvGuard, the engine of real-time scanning for AntiVir.

ClamAV is one of the most popular antivirus for Linux, but on this occasion install AntiVir.

System Configuration

This is the configuration of the system I'm using Linux:

  • HP Compaq DX200
  • Ubuntu 8.04 (Hardy)
  • 768 MB Ram
  • Linux Kernel 2.6.24-19-generic

Installing Dazuko

The software Dazuko is the most important requirement to enable the scanning on access. Dazuko was developed to enable the antivirus software's ability real-time scanning. Ubuntu repositories have an older version that does not work very well with AntiVir. To get the latest version (currently dazuko source 2.3.3-1) for Debian / Ubuntu, can be downloaded from the site via wget, typing; 


  fher98 @ betuntu: ~ $ wget http://dazuko.org/files/dazuko-source_2.3.3-1_all.deb


Installing the requirements

We need to edit the repositories and add to the list universe, come typically commented with the # sign.

file: / etc / apt / sources.list 
  deb http://gt.archive.ubuntu.com/ubuntu/ hardy universe 
  deb-src http://gt.archive.ubuntu.com/ubuntu/ hardy universe 
  deb http://gt.archive.ubuntu.com/ubuntu/ hardy-updates universe 
  deb-src http://gt.archive.ubuntu.com/ubuntu/ hardy-updates universe

After removing the sign of numeral add the words restricted and multiverse after the word universe. The multiverse repository is necessary to be able to download the Java Runtime Environment 1.4, save the file and exit.

Again in the terminal, type 


  fher98 @ betuntu: ~ $ sudo apt-get update 
  fher98 @ betuntu: ~ $ sudo apt-get install module-assistant debhelper j2re1.4 
  fher98 @ betuntu: ~ $ sudo dpkg-i dazuko-source_2.1.0-1_all.deb


Dazuko inserting the module into the kernel

We simplifies module-assistant insert modules in the kernel. The first time you run module-assistant should prepare to run as well. The command prepare to download the headers or headers of the kernel according to the kernel version in use. To add the module, type in the terminal: 


  fher98 @ betuntu: ~ $ sudo module-assistant prepare


Note: If the installation of Dazuko fails, it may be due to incompatibility in the versions of gcc. They can install earlier versions as gcc-3.4.

The system is ready to insert the module Dazuko. Run the following command to insert the module: 


  fher98 @ betuntu: ~ $ sudo ma ai dazuko


Setting Dazuko

For Dazuko not report problems when you start it is necessary to create and edit a few files. To create the first, type in the console: 


  fher98 @ betuntu: ~ $ sudo gedit / etc / modprobe.d / dazuko


In which we copy and pegamos the following code in the new document and save it. 

  dazuko install modprobe-r capability; \ 
  modprobe-i dazuko; \ 
  modprobe-i capability


As long as the root user edit the file / etc / modules and add the word dazuko at the end of the list. To load Dazuko without rebooting the system, run the following commands in the console: 


  fher98 @ betuntu: ~ $ sudo rmmod capability 
  fher98 @ betuntu: ~ $ sudo modprobe dazuko 
  fher98 @ betuntu: ~ $ sudo modprobe capability
