Hi Jan, Thanks for your posting "PCU 2.000.8 slowdown problem fixed" : http://www.wilderssecurity.com/showthread.php?t=17589 May I kindly ask you to tell us some more? - - Quote - - : There was one file missing in the PCU on the servers. About a couple of hours ago, we released a special engine update, which fixes the problem and at the same time we pulled (removed) the PCU. This solved the problem. - - end quote - - 1. Which file was missing? 2. Did we yes/no get that file with that special engine update? 3. The PCU was removed from the server; but why if that special engine update fixes it? 4. Does the following file play any part in that special update: C:\Program Files\ESET\nod32.004 Report from NISFileCheck about that file: Application: c:\program files\eset\nod32.004 Status: New added Version old: N/A Size old: 3881 Date old: 2003-12-10 01:12:20 RMD160 Hash old: 798E4BA1EE72C135777E33ADA6FB9B0A903C5087 Thanks !
