Yes, I saw that suggestion and checked. None of the Eset Folders are set to archive or index. In addition, when I go to Control panel and open Indexing Options it shows that Indexing is not running.
I'm having the same error only it seems to happen daily and I do not use Carbonite. This file renaming issue just started about a few weeks ago.
I'm running Windows 7 Ultimate 64 bit. See attached screenshot of my product. I can however manually update with no issues.
