Hi Ray

I run rkhunter on all the desktops at work, and once you tune it up it
is reassuring :-)

Hopefully you installed it from the repositories, the ubuntu version
has some nice additions that the vanilla one on the sourceforge site
doesn't - e.g. it automatically runs the update script when you
install things so it doesn't warn you about them etc.

You should also have seen warnings about some hidden files and directories.

I think the best way for you to be comfortable is to check all the
files it warns about when you are booted from a fresh install or the
live cd.

If you'd prefer something less reliable, shoot me an email tomorrow
and I'll send you my config file I use with all the relevant files
approved.
