Default Antivirus for Linux

I'm getting an increasing number of enquiries about the need (or not) for an antivirus on Linux machines, especially since distros such as Makulu have now included one (ClamAV) by default.

This is the limit of my knowledge on the subject so if anyone has concrete evidence or advice that differs from mine please post it here.

Servers are susceptible to malware infection about which I know very little but this thread concerns Linux installed desktops/laptops only. I have never known a Linux installed home PC to be infected with anything except rootkit exploits which required the user to bypass the default system security and install the infected code manually.

This product will scan your Linux system for signs of said exploits.

http://rkhunter.sourceforge.net/

Antivirus scanners for Linux are only designed to pick up Windows viruses which cannot affect your system but certainly would someone else's if they are running Windows and you mail it to them.

Linux exploits of this type where they do exist are fixed so quickly after discovery that keeping an up to date system is more important than having an antivirus installed because by the time details have been included for this, the exploit will have been fixed with system updates anyway. Maybe a Linux exploit of this type will be created and remain undetected for a period of time because anything is possible, but I have never known any Linux PC to have data compromised, deleted or stolen, nor the owners bank account contents redirected to Nigeria.

So, are Linux antivirus scanners useful? IMO yes, because especially if you use BitDefender you can check files by dropping them onto the desktop widget much more easily than booting into Windows. Additionally, BitDefender has the type of GUI Windows users are familiar with, making it an easier option to configure and run.

If you install BitDefender and have trouble setting the free key that was mailed to you, follow this procedure.

Sudo (your file manager) and open Root – etc – BitDefender-scanner.
Then copy the mailed key number (to replace that already there) into bdscan.conf and bdscan.conf.dist

Always look for a method of installing these products via your distro's repos first, or Google for instructions rather than downloading and installing manually.

I believe most of them are outdated with few exceptions. This is one of them:

Well, it must support the LTS because it successfully installed into my Makulu KDE which is based on Ubuntu 14.04.

It's odd that this subject comes to light not long after Matthew Moore spoke about security issues and how he too uses Sophos (the only viable and reliable?).

Doesn't make me want to leave Windows 7.
