I'm not sure what action we should suggest. Purging those files would
get rid of the warning, but doesn't guarantee that the installation is
safe to use. That may only hide the problem since it may be infected
by an attacker. I'm not sure how the user could detect / verify that
(realistically, you probably can't..). Running a rootkit checker from
another *nix OS may be helpful, but of unknown effectiveness.

Agreed.
