I ran msconfig after reading th' other thread and noticed a blank space in the startup menu. Nothing noted until the Location tab where it lists it as in HLKM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
That's just the registry location all startups go to. Did you look in the registry to see if their was a value for them in it? Maybe they were from apps. that uninstalled, but didn't pull everything... dunno.
