I have installed Comodo Antivirus in Ubuntu 12.04. Now it had installed, but after running it it shows to run a script.

Please help me to install Comodo Antivirus (or suggest any good Antivirus).

    I agree that you generally dont need antivirus for Ubuntu... However as Ubuntu and other distros become more common, more viruses will be written for ubuntu. So be safe on you downloads and install some antivirus.. comodo.com/home/download/download.php? try this site out and it should help installing comodo. hope this helps – user358779 Dec 15 '14 at 3:56

    I would steer clear of Comodo antivirus - it doesn't detect a good portion of Linux bad-guy viruses, and is mostly tuned for Windows viruses. Personal opinion, as an IT Security person. – Thomas Ward Feb 6 '17 at 14:44

First, you really don't need an antivirus for Ubuntu unless you're planning on dealing with windows files and/or systems.

You can download Comodo Antivirus from their website, and choose your architecture 32bit or 64bit. Once downloaded, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, navigate to where the file was downloaded (probably the Downloads folder), and run the command(s) below:

sudo dpkg -i <file_name>.deb

I would recommend ClamAV. To install run in terminal

sudo apt-get install clamav
sudo freshclam
sudo clamscan

  • Comodo does not support 12.10 yet, List of supported OS from comodo web page: Supported Operating Systems 32 and 64 bit: Ubuntu 12.04 Red Hat Enterprise Linux Server 5.9, 6.3 Fedora 17 SUSE Linux Enterprise Server 11 OpenSUSE Linux 12.1 Debian 6.0 CentOS 5.9, 6.2 Mint 13 CentOS 5.8, 6.2 – danijelc Jan 23 '14 at 11:44

In Ubuntu 12.04 the command to run the script begins with "sudo" because you have to run the script with administration privileges.

The command you type out in the terminal is: sudo /opt/COMODO/post_setup.sh

Then enter your password. Then just keep clicking "enter" to scroll down and see the "more" of the EULA, until you get to where it tells you Comodo has been successfully installed and the terminal prompts you for a fresh command for something else. Now close the terminal and you are done.

It worked for me.

To iterate, for the Comodo anti virus libssl issue, open as root, /etc/apt/sources.list, then entry/install this secure ubuntu repository, deb http://security.ubuntu.com/ubuntu trusty-security main universe; Try sudo gedit to open the sources.list file as, root.

Generic sources.list entry,

## COMODO CAV-LINUX REPOSITORY deb http://security.ubuntu.com/ubuntu trusty-security main universe;

Then, sudo apt update,

and, sudo apt-get install libssl0.9.8.

Retry, gdebi cav-linux_x64.deb, for ubuntu o/s.
