Repeatedly tried to download CCleaner 565 and continue to receive "failed -- network error"message. I use ESET AV. Help, please.

There is another post today where someone could not contact the server, it may have been temporarily offline for updating/maintenance. (Sunday is a popular day for doing that).

It's working here so you may be able to contact it now. If not then try downloading from here:
