I wonder if it is a good idea securitywise to allow traffic for all programs in firewall? I wish Bitdefender could provide better solution.
I don‘t think it is a good idea to switch off the Bitdefender firewall completely. It would be better to only exclude the MS FS app from being checked by the firewall.
I am using Kaspersky Internet security; there you have the option to exclude individual apps from being blocked. Maybe the same can be done in Bitdefender.
