You can download Mcafee by going to to there website and purchasing a subscription. Then you will be given a download. Simply press download select a folder were you would like to store the software. Launch the software and you should be prompted with a security message if you would like to give McAfee access to your folders. Click yes. The software should complete its final download now. You can also purchase a physical copy of a McAfee in popular stares like target, best buy, and Walmart. I have been using McAfee for a year and had no issues. It features tools like, quick scan & deep scan (duh) cookie cleaner, anti tracker, world wide VPN and many more. #NotSponsored
