Installing Dr.Web Anti-virus

You can install Dr.Web antivirus by running *.run file which you can download from Dr.Web website or by using old good yum. We’ll use yum method in this tutorial. Luckily, we don’t need to use DazukoFS virtual device driver for Dr. Web antivirus. First of all we must add Dr. Web repositories to Fedora’s software source lists.

• Open the Terminal (Applications > System Tools > Terminal)
• Use this command to create and open file dr.web.repo

sudo gedit /etc/yum.repos.d/dr.web.repo OR sudo leafpad /etc/yum.repos.d/dr.web.repo on Fedora 17 XFCE

• add these lines and save the file:

For 32 bit system:

[drweb]
name=DrWeb-stable
baseurl=http://officeshield.drweb.com/drweb/el5/stable/i386/
gpgcheck=1
enabled=1
gpgkey=http://officeshield.drweb.com/drweb/drweb.key

For 64 bit system:

[drweb]
name=DrWeb-stable
baseurl=http://officeshield.drweb.com/drweb/el5/stable/x86_64/
gpgcheck=1
enabled=1
gpgkey=http://officeshield.drweb.com/drweb/drweb.key

•  Update sources with the new repositories

sudo yum update

•  Make sure you have required packages on your system before to install Dr.Web

sudo yum install libglade2 unzip

• And finally installation of Dr.Web antivirus packages

sudo yum install drweb-cc

SELinux configuration

SELinux (Security Enhanced Linux) is enabled on Fedora by default. You’ll find that most people recommends to keep it enabled. Unfortunately, Dr.Web wont work correctly with SELinux enabled until some rules are not adjusted. Probably the quickest way to do that and still keep SELinux running would be to set allow_execheap (Memory Protection) value to on. However, an official warning says “Allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla“, so please keep that in mind.

sudo setsebool -P allow_execheap=1

• Check if value of allow_execheap is set to on

sudo /usr/sbin/getsebool -a | grep allow_execheap

• Reboot your machine

reboot

Removing Dr.Web Anti-virus
