Is it possible to absolutely prevent anyone from ever, ever hacking into your computer? The answer is no. On the other hand ask your self this question, Is it possible to prevent someone from ever, ever breaking into your home or office, stealing your car or for that matter robbing the bank where you have deposited your valuables? Again the answer is no. What is possible is to use basic security measures that make it more difficult for a thief to break in and lower your risk.
