Insecure Startup Item Fix Doesn't Work. Help?

Using Migration Assistant via WI-FI to set up my new iMac using the data from my old iMac. Both are running 10.8.2. Most things went fine, but now I am getting a warning box on boot up.

The box says Insecure Startup Item Disabled.

"/Library/StartupItems/Executor" is the offending item.

Using the option key, I am opening the Library from the Go Menu. There is not "startup items" folder so I am not sure where the offending file is.

I am not a great Terminal user, but wondering if there is a way to access that file.

I have tried rebuilding the permissions and that went great. There were no permissions that needed repair. I restarted the computer, but the message keeps showing up.
