This problem has been reported before. Now it is is happening to us. How do we stop it. The excessive I/O (up to 10 MB /sec shown on resource monitor) is causing all apps to slow down, and some to crash/timeout.
Also fails to load Outlook in a timely manner due to Norton add-ons - "Loading 3 of 7 Norton Antispam Outlook Plugin"
Both problems seem to have started after the latest Norton update (It took me awhile to figure out what was going on)
