Hi robinyanwang,

yes, it sure looks like you've been hacked :(

Please download Killbox:
http://www.downloads.subratam.org/KillBox.zip

And set it to delete emule.exe on the next reboot, this will make sure it isn't running on your system after a reboot.
Now, try deleting the mess.

Afterwards, you will have to check if you're still having any problems, maybe a backdoor was installed.
Try a tool like trojan hunter => http://www.trojanhunter.com/
The free trial will do fine for identifying.

If that doesn't work, do a full virusscan using one of the online virusscanners (don't trust on your installed one at this moment)

interesting...

just 5 mins, it is gone!!!

I deleted some files, folders under that folder (the hacker created),..

maybe he noticed that, so , just 5 mins ago, all 13 GB is gone!

also I can not find the emule.exe in the system thread.

Will he come back? how to stop it? he seems a good man, right?

But as that was possible still indicates that someone has full control on your server :(
So what I still suggest you is to check your system for trojans, virusses etc.

Ditto :)

If you're unsure, let us check your running processes.
