Since iOS 7, connecting an iPhone, iPad, or iPod Touch to a computer invokes a prompt to trust the PC before a connection can be established. The prompt message appears on the iPhone, iPad or iPod Touch and is designed to prevent malware from being installed on the device upon connect. Once you plug in the iPhone to the PC, you must unlock the device and accept the prompt.
It doesn’t matter whether you connect your iPhone to iTunes or to one of the CopyTrans programs. This security prompt always appears the first time you connect the iPhone to the computer.
This is how to unlock the iPhone and trust the PC
