McAfee protects computer systems, networks, and mobile phones from all kinds of viruses, spyware, malware, and other online threats. You can buy a McAfee online store from home.mcafee.com or from any of its retail stores. With the purchase, you get a McAfee activation code, which is required to activate the antivirus on your Windows, Mac, Android, or iOS device.
No matter which McAfee product you choose, you need to download, install, and activate it by visiting mcafee.com/activate. Here you would also be asked to provide your McAfee my account details along with the activation code. Yes, you read that right! The activation key is required during the download as well as activation.
Once the antivirus gets installed and activated, it starts running in the background to ensure that there are no loopholes in the security of your device. In other words, it creates a security shield around your device to protect your data, software, and applications from the cybercriminals.
