Addendum - I just noticed that your subject line references Norton Internet
Security and the body of your message is about MS Office. If you meant to
ask about a relationship between these two separate things, I'm afraid I
missed that.
Norton products are garbage. If you are experiencing a slowdown in any
situation when you have a Norton product installed, this is "normal".
Uninstall Norton and use a better antivirus program. I particularly like
NOD32, Avast if you need a free one. See if your issues disappear after
dumping Norton.
