Autorun.inf Virus Protection

A startup script to enable autorun.inf virus protection
Some virus create autorun.inf file to enable automatic file execution when you browse the folder,, which is very annoying... you can create a folder with the same name and in this case the virus would have trouble to write to that file. "Autorun.inf" even can not be overwritten because it is a folder...
Put the script at the startup to make sure every drive has a hidden folder "autorun.inf"
