I was configuring NOD32 when I realized that there is something wrong with the UI. It was all white, no icons, no background, ... Closing the NOD32 UI and reopening it, didn't solve it. I can tell you that I was running Windows 7 Ultimate (build 7041). At that moment Media Center was up and running as I was watching a live TV. Attached is the screenshot and data from SystemInformation and SysInspector (in ZIP archive with TXT extension). David.
