    rkhunter found rootkit on mine too

    Solved with Google - Apparently this is a common false positive recently

    Code:
    dav@dav-desktop:~/Downloads/rkhunter-1.3.6$ sudo rkhunter -c

    I could sit around and click "comment" all day. Instead, I'll help bring the Internet to it's knees with this signature, and a fresh download of Lucid.
