 There have been two known Linux viruses. The first was called "Staog",
and the second was called "Bliss". They haven't really made it far in the
wild, but they have been written.

 I don't know much about Staog, but apparently it does try to subvert
root. Unless it's been updated the vulnerabilities probably have been
patched (it appeared in the fall of 1996).

 More info on Staog at "http://infosec.navy.mil/TEXT/virus.html"; and

 Bliss is a less malicious virus that doesn't try to subvert root. It even
has a disinfect option; if you invoke an infected file with
"--bliss-disinfect-files-please", it will try to disinfect itself.

 More information on Bliss is at
