Disable Autorun for USB Pen drives and CD Drives

Disabling autorun for USB drives prevents a lot of virus from jumping into the system as most of the "small" guys use the AutoRun feature to trigger themselves. There is a way to disable it completely.

Click "Start / Run" and type "gpedit.msc". It should open a windows like the one below

(Click on it to open a bigger image).


In that go to the branch on the left hand side frame following the below path

"Local Computer Policy / Computer Configuration / Administrative Templates / System"

Clicking on "System" will list lots of items on the right window. One of them is "Turn Off Autoplay".

Double click on that, make sure to select "Enabled" radio button and on the list box below, select "All Drives".

This should disable Autorun in all usb and cd/dvd drives on the system.

Rebooting Mac

Mac has the uncanny habit of screwing itself up (atleast mine does) and then not telling the user what happened. Let me explain. All of a sudden, the initial grey screen comes up with the loading "rotator" thingy. And thats about it. Nothing more happens. And when I force shutdown and restart, it does not actually start from the beginning, meaning it does not do a "CHUNNNGGG" chime sound when restarting.

And again, the cloud was the Good Samaritan (who else is there). Pressing the keyboard combination of "Command(Apple)-Option-P-R" and holding it like that (NB: it needs some skill to hold this key combination) until the chime sounds twice should resolve the issue. But, my machine seems to be a bit more adamant than that. Even though I have "CHUNNNG"ed it, it still stops are the rotator screen. :-( Will update the post as and when I find a solution.
