I've had a fairly similar issue recently:
Something related to directly copying a file from inside a zip file on the c: drive to a network samba drive. The file will copy to about 40%, transfer drops to 0 kb/s, the .zip file gets corrupted, and I have to restart Windows to exit the file transfer.
Not 100% repeatable and I'm not sure how many of those specific details are required to trigger it. Extracting the .zip file before copying does seem to prevent it though, which is as far as I've gotten debugging it.
