Windigo Botnet - Is this detection method correct?

Question

After reading today about the Windigo Botnet (http://www.eset.com/int/about/press/articles/article/operation-windigo-largest-s erver-botnet-uncovered/) I used the suggested method for checking for infection, which was detailed in the article.
The code to be run is
$ ssh -G 2>&1 | grep -e illegal -e unknown > /dev/null && echo "System clean" || echo "System infected"
After running the command in Terminal, the response was "System infected".
Can someone confirm if the code given is correct for checking my OS X Mavericks.
I would hate to re-install my OS if it was just echoing back "System infected" rather than actually detecting the malware.
Can someone from Apple let us know if this is indeed the correct method of detection?

One can use the following command to determine if the server he is on is compromised:
ssh -G 2>&1 | grep -e illegal -e unknown > /dev/null && echo "System clean" || echo "System infected"
This code is missing the "$" and has the output of   "System clean"
