If 'none of the above' are working I reckon it is time for a laborious RegEdit, search for and remove all keys with the offending name, followed by search for and remove all folders in explorer/My Computer. Then reboot and pray
1) USUAL caveat - best to make a copy of the reg file first/ensure system restore available.
2) Clip junior Mostafa's firmly around the ears too and follow SD's advice in post #7
3) Password protect your laptop - why do the Mostafalets have access to it anyway?
