Norton Utilities 15.0 Scan Failure

Can anyone help?  For the past six months my Norton Internet Security application has given up during the daily routine scan of my system giving the following message.

Norton Utilities 15.0 has stopped working

A problem caused the program to stop working correctly.

Windows will close the program and notify you if a solution is

available.

There have been several updates of the application and the data but the result of the scan is always as shown above.

Can anybody help?
