How do I uninstall preinstalled (unwanted) McAffe and Avast and get Windows Defender working?

I want Windows Defender as Firewall but I can't activate it because the preinstalled McAffe Secure Line has disabled it. My concern is that while I deinstall McAffe or Avast my Acer Aspire E 17 is a sitting duck for attacks.

Should I get off the Internet during the uninstall? Will McAffe then refuse to uninstall? I know that Antivirus software loath to be uninstalled and frequently leave "souvenirs" behind. How to do this safely? I want to select my own defences. Any help will be appreciated.
