how do i use the mega unlocker?

I want to know how to use the mega unlocker.

can anybody help me?

please help me

I don't know if it is detected or not, but since it is over a week old, I WOULD NOT
use it.
It might be detected.

If you still want to risk using it,
Start MW2, and at the main menu screen of multiplayer, ALT-TAB out of it and start the .exe that you downloaded. Then change the options in the tabs as needed.

Once again, i would not risk using this any longer.

MU havent been updated since more than a month. You can't use it ATM.
