rkhunter detecta algo ¿sospechoso o peligroso?

["Gerardo A. Mirkin" <gamirkin@gmail.com>]

Hola,

Corrí rkhunter y aparecen estas líneas que me llevan a sospechar un malware ¿Es así?

[16:18:40] Warning: The command '/usr/bin/unhide.rb' has been replaced by a script: /usr/bin/unhide.rb: Ruby script, ASCII text

Además:

16:21:33] Warning: Hidden directory found: /etc/.java  (¿Cómo lo hago visible a rkhunter para que lo revise?)

[16:21:51]

[16:21:51] Info: Test 'apps' disabled at users request. (¿Cómo habilito la prueba de aplicaciones? Parece deshabilitada por defecto, porque yo no la inhabilité)
