My server used CPL Plesk, Watchdog 2.0 and chkrootkit, but I scan with CPL there is nothing. Although when I log in with SSH and use command chkrootkit to scan server and I see these :
" Checking `lkm'... You have 1 process hidden for readdir command
You have 1 process hidden for ps command
chkproc: Warning: Possible LKM Trojan installed "
After 5 minutes, I scan again and no message to be received. This is usually happen. What about these process? And what solution can be? Your are all professional, can you provide me any advice?
