For what it is worth my advice would be 'don't bother'. The best computer protection I have found is all free and consists of downloading AVG Free edition and Malware Bytes. In combination these are all you need and they won't cost you a bean. I originally got this advice from a website builder and IT expert. I have never looked back since, so forget Norton, Pccillin, Mcaffee etc, they will take your money, but are no better, and in some cases miss things that AVG and Malware Bytes will find and destroy.
