Invalid ActiveX/Com key

[SL Racer]

Norton's One-Button Check-Up tells me that there is a missing or invalid key:

"AtWorkRendering\shell\PrintTo\command

C:\Documents and Settings \ (our names) \Application Data\Aim\ubxzdljr\bartcache\D


Is this something I need to find?  How?
Is this something I need to get rid of?
