rkhunter report. Como interpreta-lo?

["Marcelo Laia" <marcelolaia@gmail.com>]

Tenho recebido relatorios do rkhunter como segue:

Warning: The file properties have changed:
        File: /bin/egrep

etc.... Todos Warning e com os mesmos dizeres: troca de hash.

Devo me preocupar com isso?

O que fazer?

Obrigado
