What is the best Malware/Virus protection program for iMac - no silicone processor
For the second time my computer has been frozen with a loud and detailed warning telling me not to shut down the computer but to call Apple at a specific phone number. I now know it is a scam. I managed to get rid of it - I think - using Safe Mode and First Air and emptying everything that could be emptied. But now I feel I need to install some protection program. Clean My Mac nearly destroyed every file I had so I do not want that program. Any recommendations from a MAC specialist? iMac Retina 5K; 4.2 GHz; 1 Processor; 4 Cores, 16 GB
