Hello there,
Both antiviruses offer excellent protection against real-time malware attacks, phishing, and other online threats, but Microsoft Defender offers near-perfect protection, while McAfee protects you from 100% of threats online and offline.
Microsoft has made some great improvements and developments over the last few years when it comes to Windows Defender making it a great security software these days. It will not slow your PC, it is Free and will work for most of the web browsers like Chrome. I recommend not to renew your subscription with McAfee and start using Microsoft's built-in Security software.
Hope this resolves your Query !!
