J, Did it work for you eventually?
I don't see this message in your log "Please provide the following cf-ray id with your ticket: ..." That makes me wonder if you were blocked by Cloudflare or by a different firewall. Another idea worth testing if it still isn't working -- you could delete the "freshclam.dat" file from the install "database" directory and then run freshclam.exe again to see if that resolves it.
