Since the Sim Update 3, every time I start MSFS2020 Norton flags it as not having a valid digital signature. Is there an issue with the update?
Sounds like a False Positive from Norton.
More likely an issue with Norton
Another user on this forum has described an issue with Windows Defender Firewall also.
Does the Norton warning show a path to the module it doesn’t like?
I attached a screenshot… may have shrunk it too much, but hopefully you can see the file info (at least the format of it).
