In my specific case, I needed a script to automatically and quietly remove Norton Antivirus Corporate 7 in preparation for the deployment of Symantec Endpoint Protection 11. According to documentation, simply going to Add/Remove Programs and uninstalling it doesn't entirely do the job. This script performs a full uninstall using the program's GUID. Simply rename the text document to .bat and run it on a Windows XP or Server 2003 machine. Enjoy.
