George and Drphibes - Thank you for your responses.

It turned out to be quite easy once I knew what the problem was.  I simply reinstalled using the Websetup21 program and it reinstalled cleanly with no issues from my antivirus software.  All I had to do was confirm that I wanted to overwrite the existing program.  I didn't have to mess with Zone Alarm.

Apparently, there was something about the update that got the file caught by the antivirus program.

All good now and running smoothly.
