This usually happens if you are currently running a form of anti-virus software on your computer. The shield will indicate a threat that the software believes may come from loading a certain program such as iTunes.
When you bought the anti-virus software it would have come with a set of instructions in the box. It is always advisable to read these thoroughly as it should explain how to allow a certain program to run even when the software is trying to block it. However you should be careful not to ignore what the anti-virus software is saying as if you do open a program it has indicated as dangerous then you could harm your computer.
Without knowing the software you are running and even the operating system, no detailed procedure can be accurately given. It is best to consult your instructions or seek advice from a computer specialist.
