I just ran through it and I don't think it installed it. I followed your guide to a T and typed in chkrootkit and got the wonderful bash command not found. Just thought you might wanna run through it real quick to make sure I just didn't mess up in some way.
BTW your website is a very nice pool of knowledge and I do appreciate it being as new to linux as I am. Your website is greatly appreciated
.
EDIT: found your problems [A:] you need to be in the program directory and [B:] it's ./chkrootkit not just chkrootkit
At least this is the way it is for me maybe as I said above I might have messed up or need to reboot but whatever thought you might wanna know.
