I am using Webroot SecureAnywhere version 9.0.31.86 Have installed software MSFS2020 Map Enhancement which only functions when WR shutdown protection is activated. With WR active program advises: Error: Stop server failed, error: Error: EBUSY: resource busy or locked open. C:\Windows\System32\drivers\etc\hosts My host file is basic default. Software developer advises: If it is hosts related issue, please check with your antivirus I have allowed MSFS2020 Map Enhancement.exe within Active processes of WR. Windows Defender Firewall also permits MSFS2020 Map Enhancement through my Public Networks system. I am at a loss to further rectify the problem and would appreciate assistance from our tech guru's when time permits noel1947 Noel Southam
WSA will protect the Hosts File so uncheck this box under Advance Settings/Shields and save to see if that works.
Others reported too issues with FlightSim and the Hosts file, see: https://www.avsim.com/forums/topic/584425-your-bandwidth-too-low/ (not in particular related to Webroot). I haven't read the whole thread and I leave it further to others, but I thought I mention it in case it might help.
