We now have reports of this on AVG, Avast and possibly Kaspersky.
You need to make sure all these apps are in its exceptions lists:
dowser.exe (in the Steam Steallris folder)
C:/users/<UserName>/AppData/Local/Programs/Paradox Interactive/launcher-v2.2020.16/paradox launcher.exe
C:/users/<UserName>/AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe
Good luck!
