Dolphin.exe triggering a rundll32 on boot doing massive disc I/O

[Aleron Ives]

You may also want to check msconfig's list of startup items to see if one of them invokes rundll32.exe. If you suddenly have a new entry that's unrelated to the software you run intentionally, then it's malware. It's definitely not related to Dolphin, though. Dolphin doesn't create any startup entries either in your Start Menu startup folder or in the registry.
