data security

I have a data breach on my home computer. There is an individual using my account for monetary gains, with my work, education, experience, as well as my family information. My son has Master's degrees in General education, my daughter is an artist, and our information is used to gain employment opportunities by outside people. I opened this account in Jan. 2017 as a Learning Coach for my Honors, Program 8th grade daughter. It is connected to my Live account, I am an inventor, the education, as well as achievements are treasured.
