RUNDLL Errors on Startup

Every time on windows start up I get the 2 following errors: "RUNDLL Error Loading C:\Documents and Settings\Alton Horsley\Local Settings\Application Data\advPathNet\BluetoothcrtLite.dll The specified module could not be found" and "RUNDLL Error Loading C:\Documents and Settings\Alton Horsley\Local Settings\Application Data\eCommonlink\CRLAuthenticationmon.dll The specified module could not be found"

I was trying to determine what they were but had no luck. So I am not sure if these are caused by spyware or just remaining entries from programs that were deleted etc? I read here that I should avoid registry cleaners, but I am not sure how to get rid of these rundll errors then. Any help/advice is greatly appreciated.
