Hi, My father-in-law had this scareware pop up and without consulting anyone called the number. Here is the blue-screen of death popup. He is on os x el capitan. http://imgur.com/FNhstAs I don't have all the details but he apparently called the number and let them take remote control to "clean" his system. I imagine it is just a browser hijack that sends Chrome to that site. He restarted his browser and it kept on popping up. I checked the 844 number he called but there is no info on it. I am also wondering about the site listed on the popup. It seems like it is a fake site since i googled the site name and couldn't find any listings. Anyone had this happen to them and can you provide any tips. I think he had a password manager(or icloud keychain) and they probably have access to his email, bank account, etc. Thanks.
