I saw the history on my Mac to see what it was I downloaded. It was an app called Any desk. I had to type in a verification code. This must have been where they gained remote access to my desktop. I deleted and removed this app. Never knew about remote access to a computer before. While it might serve some benefits, it can be a dangerous tool in the wrong hands. I guess not knowing enough about the IT world is just as dangerous. I will keep you posted on any recovery and the process if it helps any be just a little wiser for the experience.
This digital world is too much for us insects to understand.
