How to cancel sync file transfer

I have the desktop synched to my online Zone account.  I made the mistake of trying to backup a very large folder, about 2.5GB with thousands of files, by using a backup program automatically write to the local folder C:\Documents and Settings\Administrator\Norton Zone\"myfolder".  The transfer has been going on for days and continues to show 15 hours remaining.  I have concluded this doesn't work, but now I can't stop the ongoing transfer. 

 

The backup program shows the file transfer complete and successful. 

 

I have deleted all folders showing the double arrow of ongoing upload, both online and in the local folder.  If I now open the local folder, all items show the green check.  But the taskbar icon continues to show the arrow, and a mouse hover shows the same 15-hour transfer of some 60,000 files going on.

 

How do I stop this file transfer?

thanks,
