I am using Ubuntu 11.10. I installed Linux Malware Detect (LMD) v1.4.1 and ran it. It reported the following infection.

I did a search for this infaction and found this info. It makes it seem pretty bad but it does not say how to get rid of it. I set LMD to clean and quarantine infections but it found this infection after two runs.

What is the best way to get rid of this infection?

Thanks,
Peter.

Unlike with the Other Platform software vulnerabilities in Linux commonly are not, and should not be made subject to, "erase and be at ease"-type of cleaning up. It's unfortunate to see LMD tries to shove such a "solution" down your throat. Software vulnerabilities in Linux commonly require you to verify software integrity and update software.
You should always inform yourself well enough to be able to assess the problem (that IMHO is "the Linux way", not "erase and be at ease") and this is best done using any CVE identifiers with which you consult:
0. your distributions security information: Ubuntu: CVE-2008-2044 and in your case upstream Debian: CVE-2008-2044,
1. the vendor site: netOffice Dwins,
2. the CVE: netOffice (or the OSVDB, NVD or Secunia) and see details at CVE security vulnerability database: CVE-2008-2044,
3. Determine if the machine you run LMD on serves web pages or web applications and if it specifically runs the vulnerable version. Only if it does, then:
- check directories and files the user the web server runs as has access to for anomalies like uploaded files,
- check your login database and system logs for anomalies and your web server logs for access where either 0) files like "projects_site/uploadfile.php" are in the URI or 1) where the "demoSession" variable is set to "1",
- know from the vendor site version 1.3.1 was released as a fix on 2008-04-22 and the current version is 1.5.

HTH

I guess your malware scanner just stubled of a detection file from nessus,
(.nasl files are just nessus detection patterns)
http://www.tenable.com/products/nessus/

It's like one anti-virus regards the detection-patterns of a second one as infection in the win-world

So nothing to worry about, if you have Nessus installed

Actually the link you provided says it all:

"I think", "don't worry" and other such fuzzy human phrasings are what we like to avoid in this particular forum. If you did actually read my reply you should dig that sharing knowledge and tools (aka giving a man a fishing rod) trumps, and should trump, "don't worry" responses (giving a man a fish) each and every time.

First of all my answer was "So nothing to worry about, if"

Secondly I read your answer and all the links provided and I could nowhere detect a hint to Nessus.

If you read the OPs question you'll read
Which is not in any way a file which belongs to netOffice Dwins

but a Nessus Plugin or a file witten in the "Nessus plugin language"

Ahhh! Now I realize what you mean.
Yours is the right answer.
My apologies.

You're welcome, don't worry

I just had several times already the situation, where a possible security problem turned out to be detection pattern files from different security scanner or anti-virus software, which simply played "detection ping pong" with their respective pattern files ...

Well, that doesn't detract from the fact that I just should have read the OP more carefully...

I would like to thank you both for your responses. They have been very enlightening. So far I'm liking LMD since the installation and operation is straight forward although I was fooled when it picked up the Nessus file. I guess it was more of a weakness in an older version of Nessus, in that things could get through, rather than actual Malware.

Thanks again,
Peter.
