Hello TalkerCat,
Visualbee plugin is used enhance powerpoint presentations to showcase a powerful creation, often promoted as a free add-on during free downloads. Since it is not a malware, Norton won't be deleting or detecting it as a threat. You can go to your browser extensions and disable the Visualbee add-on, and then uninstall it via Control Panel in windows.
If you still suspect a virus, you can try to run a scan with our Norton Power Eraser:
Let me know if you need further help with using Norton.
Thanks!
