Microsoft windows defender flagging encrypted WinRAR files.

Hello, I uploaded Music files to Mediafire for many years now and all are being flagged as Trojan:Script/Wacatac.H!ml by Microsoft security… I’m referring to password-protected and encrypted Winrar files. I uploaded a handful of the files to virustotal which found no issues with any of them. These are simply flac music files I have uploaded, and each download fails to finish with the message “download failed virus found.” If I disable encryption and remove the WinRAR password, nothing is picked up. This cannot be accepted . Any opinions or suggestions on this? I’m grateful. BTW I also attempted to download a few of the files using a different computer with a different internet provider and the same problem occurs.
