Norton AntiVirus 2003 System Integrator

Window XP Professional
I am continiously getting a Norton AntiVirus 2003, System Integrator message, when I try to scan my hard drive.
System Integrator could not intialize the current frame class. Please make sure that you did not directly run the integrator.
How do I solve this problem, I already try uninstall and reinstall,the problem keeps coming back?
