Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.

You don't need any AntiVirus protection on your Mac since you are using latest macOS. Latest macOS has system integrity protection enabled, so virus or malware can't compromise the system. Not only that Apple releases and patch any vulnerable loop holes in macOS by security updates.

The issue is caused by the Firewall of MacAfee. Open McAfee and do you see any Firewall section ?
