OK disabling BitDefender got the files DL'd without being blocked. But now I'm in a loop - version 40 files downloaded - click to relaunch. It relaunches at version 39. DL version 40 files again - click to relaunch. Relaunches at version 39, etc. etc. UGH.... Guess I'm stuck at 39.xxx

False positive.

Yes, but that info does not help get Opera updated. Can you contact BitDefender and inform them of the situation so they fix this? No way to "white list" those files from the client as far as I can tell.
