Just because it was encrypted doesn’t mean google can’t run some processing. For example encrypted zip files still can show the file names. These file names could be specific or malware or a collection of matching file names.

This is why I said zipped then encrypted, yes any pattern matching like filenames could be used to identify malware.

Plus encrypting then zipping removes any compression opportunity so that's just a bad idea.
