Word 2003 scans for virus

Specs. Norton Internet Security. Win 7.

Problem: Recently despite Word 2003 being use for 10 years I had a change of behaviour of MSWord. It would with each word document  being opened slow down, and indicate "running virus scan" in task bar at bottom screen.  THis is a big problem as I open these word docs all the time, and have to wait and wait for them to open.

 

All posts say that this is a third party app security problem. I only have Norton, and have had it for a couple years.

Following made no difference.

1.  -  disable anti virus autoprotect

2.. Microsoft automatic scan 'off'.  It was on.

3. Change word normal .dot template. 

 

Any ideas?
