A. Dluca.exe is an adult material dialer process that can use a large amount of resources. You can safely remove this process, and after you do, your system resource use should drop. To remove dluca.exe under Windows XP, delete the \%systemroot%\system32\msinstall\dlu32\dluca\ folder, then open Msconfig and navigate to the Startup tab to remove any dluca.exe startups. For other OSs, use the registry editor and delete any entries under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run registry subkeys.
