As i see, this issue take place in others ESET product https://forum.eset.com/topic/16310-problem-in-endpoint-updating/
So, maybe problem lies on server update side ?

About week ago antivirus began update module program automatically every hour or when i check update manually. And there is only show update process 1/1 and no any update download.
I clear update cache and restart PC but this not solve problem.
