1.I did not connect the network serve or let anyone to remote control my computer.
2.I disabled the "Root User".

I believe that your Guest User is enabled. Go to System Preferences> Users, and click on "Guest User" (you may need to click the lock on the bottom and unlock it first) then uncheck the box that says "Allow guests to log in to this computer"
