Boot into SAFE MODE, then go into msconfig again, START UP tab.
write down the Registry Path (look to the right of the program) NOTE: you might have to hover the mouse pointer directly to the left of where is says, "location", and slide it over to the left, to be able to see the entire registry path.... Next open a RUN command and type:
regedit, click OK
Then navigate to the registry location that you wrote down and delete program from the registry
You could also try going into the SERVICES tab in MSCONFIG, click "Hide All Microsoft services", then locate the problematic program/service and disable it
