Top 5 Anti virus for Ubuntu

Generally Ubuntu Linux is hardly effected by virus and the reason is its structure and strong community support, any loopholes are worked immediately. For every new virus, its solution is out within two hours thus preventing it to do any further damage. Linux antivirus are also effective against the Windows virus and they are removed if they enter your systems through external hard drive, internet etc.

Top 5 Ubuntu Linux antivirus I recommend are:

1. ClamAV Antivirus 
ClamAV is the most popular open source anti-virus software and it is available for both Ubuntu and Kubuntu. Its GUI interface is called Clamtk.
It can be install from the software center or in terminal type
$sudo apt-get install clamav clamtk

3. AVG Antivirus

Bitdefender works perfectly in Ubuntu 12.04 x64. It installs cleanly and the gui shortcut appears in the menu after a system restart. Updating and scanning works ok.

Avast was not allowed to be installed by the ubuntu software center, due to lacking conformity to strict debian packaging policy.

I couldn't find how to start the gui for avg. The command line and update worked.

Also tried avira, but could not find out how to start it.

My bank uses Linux and they also use AVG, so naturally, I use AVG anti-virus :D

Are all/any of these active after installation? I.E. running a service for real time monitoring.

The rule of thumb in Windows is only one AV package at a time. I would like to know if I can trial more than one of these at a time.

Well the things is good here for helpful for all.

I've installed BitDefender antivirus. when i open, there is an error "Loading the antivirus engines, Please wait"

The command $sudo avggui does nothing on my 12.04 when trying to run AVG 2013 flx-r

Tried to install BitDefender using instructions above. Everything worked up until installing the GUI. Terminal said it could not locate package bitdefender-scanner-gui.

drop the "$" it appears to be a pasting error

Linux is commonly known as the virus-free operating system. Because the common virus system is created to run on windows operating system which has no function when opened on Linux.

Great thread and currently running ClamAV as I type.
So far it's found 89 "Threats" and it hasn't finished running yet.

I haven't installed because I'm worried about this machine because as yet we don't appear to be a target for people who make viruses... I'm doing it because I don't want to send something to a friend who's running a Windows OS and they have no protection.

This was a really wonderful post. Thank you for your provided information.

Thanks very much for this info.
well now... avast and avg both crashed on my laptop, and also on my sisters PC running windows SO I wouldn't touch either with someone else's computer.

So I'd use Clam with its GUI
Comodo Anti-virus on Ultimate Edition Linux, as I do on my Win7 side of my dual boot.
And it is working great on Mint 16 on a usb stick as a trial distro to maybe replace UE, someday? Or just Tri-boot.
Thanks again.

Add the following line to the /etc/apt/sources.list file:
deb bitdefender non-free

and then run:
sudo atp-get update
sudo apt-get install ...

With obvious malware affecting my computer (Ubuntu 14.04), I installed clamTK, which found numerous threats, and deleted them. However, noticed that they were all located in browser (Mozilla Firefox) cache.
Later, I ran it, noted it detected 18 new threats. I did not delete them, then I emptied the Mozilla cache. Ran clamTK again, and it detected no threats.
So, the malware does not affect Ubuntu, ony Mozilla, It takes time for clamTK to scan the computer, and it is much faster to just clear the cache than to do a scan with clamTK.
