Hello Mustafa,
If I understand correct, kloxo-mr installed rkhunter, right? In that case, it would be correct to add rkhunter --propupd. Without this, it will not function.
It is possible that this was installed from centos template. Even in that case, it would be worth to have something like this integrated.
I got the message:
The file of stored file properties (rkhunter.dat) does not exist, and should be created. To do this type in 'rkhunter --propupd'.
