I have NEVER chosen to have a public network. Yet every time I reboot, it is a public network. To change it back to a home network requires me to make two administrator changes. What can actually act as administrator on my system? It changes from home network to public. It also changes the file sharing and discovery options to allow them, and I NEVER do that. To return both of these changes to what I want, each one requires my authorization as administrator. As usual, I run S&D and other antivirus scans - and as usual, nothing. I need advice. I can cope with changing these every day, but what ELSE is this malware able to do that I haven't found yet? Thanks for all the good help you've given me in the past, Holly B.
