System checks summary
=====================

File properties checks...
Required commands check failed
Files checked: 132
Suspect files: 4

Rootkit checks...
Rootkits checked : 245
Possible rootkits: 0

Applications checks...
Applications checked: 4
Suspect applications: 3

The system checks took: 4 minutes and 44 seconds

All results have been written to the log file (/var/log/rkhunter.log)

One or more warnings have been found while checking the system.
Please check the log file (/var/log/rkhunter.log)

nah setelah melakukan scanning, kita biasa melihat bahwa ada file yang terdeteksi berbahaya yaitu dengan tanda warning.
tapi anda jangan kawatir dahulu karena peringatan tersebut belum tentu bersifat negatif, kadang bersifat positif karena kita memerlukan file itu untuk tetap aktif
makanya anda harus benar" tahu file mana yg anda memang benar aktifkan.
makanya dari itu sering"lah anda melakukan scanning untuk keamanan komputer anda..


moga bermanfaat.
