The Linux operating system, along with Unix and other Unix-like computer operating systems, is generally regarded as well-protected against computer viruses . There have been successful attacks, however, on both Linux and Unix systems, the most notable perhaps being the Cuckoo's Egg attacks on Unix systems in the 1980s.
The number of viruses specifically written for Linux has been on the increase in recent years and more than doubled during 2005 from 422 to 863.

 Linux vulnerability
Like other Unix systems, Linux implements a multi-user environment where users are granted specific privileges and there is some form of access control implemented. As such, viruses typically have a diminished ability to change or impact the host system.
One of the vulnerabilities of Linux is that many users do not think it is vulnerable to viruses. Tom Ferris a researcher with Mission Viejo, California-based Security Protocols said in 2006, "In people's minds, if it's non-Windows, it's secure, and that's not the case. They think nobody writes malware for Linux or [Mac] OS X. But that's not necessarily true...."
Shane Coursen a senior technical consultant with Kaspersky Lab noted, "The growth in Linux malware is simply due to its increasing popularity, particularly as a desktop operating system...The use of an operating system is directly correlated to the interest by the malware writers to develop malware for that OS".
The viruses listed below still pose a potential, although minimal threat, to Linux systems. If an infected binary containing one of the viruses were run, the system would be infected. The infection level would depend on which user with what privileges ran the binary. A binary run under the root account would be able to infect the entire system. Privilege escalation vulnerabilities may permit malware running under a limited account to infect the entire system.
The use of software repositories significantly reduces any threat of installation of malware, as the software repositories are checked by maintainers, who ensure that their repository is malware-free. Subsequently to ensure safe distribution of the software, md5 checksums are made available. These methods of attack can be defended against using repositories protected by digital signatures which prevent the hijacking of communications using a man-in-the-middle attack or via a redirection attack such as arp or DNS poisoning. This limits the scope of attacks to include those that have administrative access to the repository itself.
 Cross-platform viruses
A new area of concern identified in 2007 is that of cross-platform viruses, driven by the popularity of cross-platform applications. This was brought to the forefront of malware awareness by the distribution of an Openoffice.org virus called Bad Bunny.
Stuart Smith of Symantec wrote:
 Anti-virus applications
Virus scanners such as the open source Clam AV and the commercial freeware Avast! and AVG are available for Linux.
SecurityFocus's Scott Granneman, says:
"...some Linux machines definitely need anti-virus software. Samba or NFS servers, for instance, may store documents in undocumented, vulnerable Microsoft formats, such as Word and Excel, that contain and propagate viruses. Linux mail servers should run AV software in order to neutralize viruses before they show up in the mailboxes of Outlook and Outlook Express users."
