Hi, My sister has a 2014 Macbook air, and she has been asking me to help her, as she has a virus or some sort of malware on her Mac. I suggested she just download malwarbytes which came back and removed some stuff from her mac, but she still gets the message when she uses Safari. I suggested she reinstall OSX, but she not to keen on it. She made the silly mistake of calling them, but then hung up when they wanted access to her Mac, and she says her internet now only works sometimes. Anyone have any ideas how to get rid of it?
