I downloaded an image from iCloud, which ends up as a zip file containing a JPEG file and a MOV file. This is because the iPhone takes a motion image (MOV) over a brief interval of time, and then generates a JPEG still image.

Firefox complained that the file contained malware, which required me to explicitly allow the download. I then scanned it with with Windows Defender. All seems fine.

This seems to be due to some weird interaction between Firefox and Windows Defender. How is it possible for Firefox to get triggered by the download when the AV says it's fine?

After allowing the download, further picture downloads don't trigger the warning. From the Firefox download history, the message is "This file contains a virus or malware -- iCloud-content.com".
