How can I protect myself from the whispers of Satan?

Protection from the whispers of Satan is achieved by being wary of him and remembering his enmity. The greatest way to be protected from him is to adhere to the Qur'an and Sunnah, both in knowledge and practice, to seek refuge in Allah from Satan, to be diligent in the remembrance of Allah Almighty, to choose righteous company, and for the servant to hasten to repent to Allah if Satan misleads him.
