What McAfee software are you using Bill? Just a name & version number if possible would help.
Sorry about that McAfee Internet Security latest version.
There are two things to try then.
1. Make sure permissions are full in Web and Email Protection > Firewall > Internet Connection for Programs and you could experiment there with tuirning off Netguard to see if that makes a difference also.
2. Submitting the software for clearance, although it hasn't exactly been quarantined I suspect it is being identified as a PUP. See HERE.
I forgot to add that unless a tech drops in here, which may or may not happen, Technical Support could probably be of more assistance and it's free by phone or online chat. See the link under Useful Links at the top of this page.
