Hello, I also had this same problem with all trainers of Mr AntiFun with my new computer and Windows 10... It is sufficient to let the anti-virus to eliminate the trainers and to reload them on the site of Mr AntiFun. Then the anti virus Windows Defender doesn't detect them anymore as virus... I don't know how to make if you have an anti-virus other, on the other hand, as Nortons and other scums.
