In this instance the downloaded file was in Opera cache and the download location was in one of my folders, and the release process took about a minute, which seemed quite long considering the file is only 1.5meg. The only reference I found to the "released file" query is, without an answer, here: https://www.wilderssecurity.com/showthread.php?t=236205&highlight=amon: released file This was under NOD32, v3, build 4194 on XP-home SP3. Today's build is 4197. That was for Peer Guardian2. Known to me. I also see under 4190,4107,4035 that PortLoop, whatever that is.
