Special Note: Make sure Windows Defender and Windows Firewall are disabled before installing Sophos
The article doesn't specifically tell us HOW to disable WD and WF. I am not convinced it is necessary to disable WF, since the Sophos Firewall installation should disable WF. Right?
I can understand disabling WD, because we don't want it running any services in the background. I just wish Sophos would disable WD during installation.
