I have a large client with 2 of their workstations exhibiting this problem. Both workstations have previously been OK with updates working. In the last month there has been excessive downloads traced to these two PC's. Cost them $2K in excess bandwidth. It was traced to failed NOD32 updates. NOD32 is showing old files on both (same date ... 20070208 ) Update starts and gets to about 60% of an engine update then fails so retries another server. (It gets about 5MB of an 8MB update each time). The result is that continuous retries are causing up to 1GB / day and it never completes. De-install/Re-install of latest NOD32 does not help. Any ideas appreciated.
