Overseer.exe found by Firewall

Hello,
a couple of days ago i installed avast free antivirus. Today i got this message:

I know Overseer.exe is from Avast itself, but why it says it is not signed? On the top it says missing signature.
But when i look at the file at properties and digital signatures there is a Avast Software s.r.o. signature.
Was my overseer.exe infected somehow?
Thanks

This is a bug in the verification code (used by the firewall dialog) which sometimes incorrectly shows the file as unsigned even though there’s a valid signature.
I can see the related ticket as closed, the issue should be fixed in the upcoming v23.6.
