You should shut down your server and start it in the rescue system.

Then try to understand how your server was compromised and remove the cause.

You probably have folders and / or files with 777 permissions, that needs to be changed to 755.
(For example, if you want to upload PHP extensions (= WRITE) and then start them (= EXECUTE), you need: chmod 777)

You should reset your server to a backup status that was definitely before the incident and then correct your folder and file permissions immediately.

Until the exact causes are known, I've written a provisional script, which is executed as root via cronjob
Code: 
@reboot /root/malwarekill.sh
You can of course let this run every 60s.

/root/malwarekill.sh rights 700

Code: 
#!/bin/sh

kill $(pidof kdevtmpfsi)
kill $(pidof kinsing)
rm /tmp/kdevtmpfsi
rm /tmp/kinsing
rm /var/tmp/kdevtmpfsi
rm /var/tmp/kinsing
echo "everything is good here" > /tmp/kdevtmpfsi
echo "everything is good here" > /tmp/kinsing
echo "everything is good here" > /var/tmp/kdevtmpfsi
echo "everything is good here" > /var/tmp/kinsing
chmod 644 /tmp/kdevtmpfsi
chmod 644 /tmp/kinsing
chmod 644 /var/tmp/kdevtmpfsi
chmod 644 /var/tmp/kinsing

In /var/spool/cron/crontabs I create a file named ftp owner root:root 644

For me, the malware no longer runs if the script runs once at boot.
Otherwise the malware sometimes came back 10 hours later.


PS:
Today I have reinstall the server.
