StarSeanyBoy, since AVG version 7, the email plugin of it is not compatible anymore with avast mail scanner.
Besides this, Windows can load in a different order the services and legacy drivers. Consequence: trouble and conflic.
I've used AVG as a non-resident scanner in the past... Security Center, one day, detected it and ignored avast, the real resident antivirus...
Since then, no more AVG

Make sure the avast plugin is not disabled into MS Outlook:
Outlook 2003 > Help > About > Disabled items
Outlook 2000 > Tools menu > Options > Other > Advanced Options > Add-In Manager.
