Lori googled how to remove remote access apps on her Mac, and she was able to remove them after Apple walked her through it. But she's worried that she didn't get it all. Leo says that if Apple took them off, it's a good chance Lori is fine. It's easy to get paranoid about a computer because it does a lot of things we don't understand. The only concern is that when Lori gave the original technician remote access, that he could've installed something else she doesn't know about. If she's really worried, she can always back up her data, format her hard drive, and then reinstall macOS. But that's a drastic action. Keep an eye on it, and put a piece of tape over the webcam.
