Hello, I try just for informations chrootkit on my el capitan. It said few days ago that windigo is in. Well, ok... I did some research and studies tell thats its on servers and you have to tape in Terminal: ssh -G 2>&1 | grep -e illegal -e unknown > /dev/null && echo “System clean” || echo “System infected” And I have “System infected”. Ok... Then I reinstalled El Capitan following what is recommended. And now I just do some research on Google just to find the command line, and I tried to not to be online during the install, I tried the command line and guess what? “System infected”!! What's wrong with that command line? Is it unix command? I am a few aware about command line in Linux but ssh -G i didn't know, and all that command line I don't understand very well what its expecting in a mac... Well should I be worried or no?
