Windows Defender provides basic antivirus protection and is generally considered to be sufficient for most users. It offers real-time protection against viruses, malware, and other security threats, as well as the ability to perform regular scans and remove any detected threats.
While McAfee does offer additional features such as firewall protection and identity theft protection, Windows Defender has been shown to be effective at detecting and removing viruses and malware. Additionally, Windows Defender is updated regularly through Windows Update, which helps to ensure that it stays up-to-date with the latest threats.
Also, McAfee offers dedicated customer support, while Windows Defender relies on Microsoft's general support channels.
