How Remove Symantec Quarantine From Application Data

How do I remove Norton Quarantine folder?

 

I removed Norton via the uninstall utility after my ISP Verizon-Yahoo stopped offering it as a free service.

 

A quarantine folder remain in My Computer\C:\Docs and Settings\All Users\Application Data\Symantec\SRTSP\Quarantine.

 

System won't let me delete it.
