I already did the procedures to delete the xhunter folder in reg editor, started the game and then I couldn't find the process again in Process Hacker.
There is another way to solve that problem? What I've done:
6. Now go to "Security" TAB and open it. Click the little box "Deny" access at the top right of that list. (This point was Ok, I've denied access for all the users that could exist, but unconsciously, I've pressed Ok and then the process gone)
7. Now click "Advanced" and open. Remove the bottom 4 (64bit) only with access rights. <- I can't do this part because I can't access the fking process!
So, if anybody else can help me, I'll be really greatful.
