  1. As a Linux system, Fedora has much less possibilities to be infected from a Virus (compared to Windows)
  2. Fedora is one of the most secure desktop systems I have ever used. It comes with pre-installed, but most of all, pre-configured firewall(FirewallD) and also the ultimate SELinux tool.
  3. Generally you don't need an antivirus in Fedora. Viruses for Microsoft Windows do not affect Linux systems. But if for any reason you want to install one, use clamav, it is available in Official repositories. (clamtk is the GUI front end).
  4. Read the basics on security.
  5. Relevant question, multiple answers, same result = no antivirus is needed.
  6. Always keep in mind that the best AntiVirus for a system, is the User itself !

There is a very small likelihood of a linux system getting infected with viruses. There are few Linux viruses in the wild - http://en.wikipedia.org/wiki/Linux_malware#Viruses . If you want to check, you install clamav and clamtk (GUI for clamav) and run a scan.

There are also tools available for scanning the system for rootkits - chrootkit and rkhunter are popular. rkhunter is available in the repository and can be installed using yum.

For the sake of completeness - While linux systems are unlikely to be affected by Windows viruses, it is possible to pass the virus from an already infected file to another windows system. So, using anti virus solutions like ClamAV might be a very good idea for the sake of eliminating viruses.

Of course, you can not be sure that your computer is, and ever will be, free from malware. While Linux has a relatively low market share for standard personal computers, this relation is not true when it comes to servers or mobile/embedded devices. So, of course there is a large incentive for malware developers to target Linux systems as well.

This blog entry quite plausibly debunks the myth that Linux systems can be considered immune to malware no matter what:

To cite the, in my opinion, most convincing point that is made:

3 – Windows malware cannot run on Linux.

Not exactly, truth be told. Although their number is still pretty low, there are more and more cross-platform threats. This is due to the multi-platform frameworks which are available nowadays also under Linux. Frameworks such as: Adobe Flash and Reader, Java, JavaScript, Perl, PHP, Python, Ruby, etc.

So, we will see more of this kind in the future. Therefore, you totally need a anti-virus or malware scanner, even using Fedora.
