I experienced this problem a few days ago, the quickest solution I could get was the following:
Use the following command:
ls -l /proc/<PID_of_process>/exe
This command shows the position where the process is running. Create this folder.
Remove all the permissions for all users:
chmod o-rwx /tmp/<name_of_folder>
Then kill the process:
kill -9 <PID_of_process>
Kindly run below one liner bash shell script inside crontab every minute and it will kill the virus in a scripted way.
kill -9 $((ps -aux | grep -i 'kdevtmpfsi\|kinsing\|kthreaddi') 2>/dev/null |grep -v grep |awk '{print $2}')
