"Trial" watermark

How can I get rid of the lady saying “trial” during my recording? I have uninstalled and reinstailled a number of times based on what I’ve seen on the internet - to no avail. I have version 2.3.0

Audacity does not have a “watermark”. The watermark is probably coming from a demo plug-in that you installed some time.

Perhaps you have “AVS Audio Tools” installed? The trial version of AVS Audio Tools is known to cause this problem.
