Restart your computer and without opening the Roxio program see if it's still running in the background. If it is it's running at start up.
Go to Start/Run, type 'msconfig' in the Run box and click OK to open the System Configuration Utility. Choose the Startup tab. Scroll down the list and find the Roxio application. Uncheck the box next to it. Restart. That will stop Roxio from loading at start up.
