I am working currently on a software which I am packing into an NSIS installer and distribute the resulting exe file. The installer must run primarily on Windows 10. Since a few days, Bitdefender added protection against ransomware. Since my installer tries to write to the Documents folder for the current logged in user, the installer is being blocked by Bitdefener as potentially malicious. How can I fix this? Should I not write to the Documents folder? Is there another appropriate folder? Can I sign my installer or is there some other method that makes this installer trustworthy for Bitdefender?
The file which I am writing is an .xlsm file. While I agree that this is not the best file format to create in terms of security, this is the file format I am currently having and there is no quick way to change this.
