Hackers are everywhere. They look just like you and me; you might see them in a grocery store, online at the pharmacy, or sitting at the table next to you at a restaurant, but you would have no idea of the capabilities they possess. By definition, a hacker is a person who illegally gains access to and sometimes tampers with information in a computer system. This means they have the talent to install viruses and malware that can allow them access to your personal information and the unauthorized use of your computer.
