Not known to me. You can probably get rid of the icon by right clicking your taskbar, choose Properties, then Customize.
But that will only get rid of the icon, at the most. Something / someone has got the icon there, and that you need to get rid of. Check what you have installed lately, uninstall them one by one, to see if it helps. Also, run a thorough AV scan, maybe Malwarebytes and CCleaner, the latter also with registry scan. For program uninstall I usually prefer Revo Uninstaller.
More and more programs come with attachments, it may be something as innocent as "an extra voice control", or whatever, came with a game, or something. Something that just simply came along with something... No need to be truly worried. But like you do, hopefully, take care of your teeth, pay some attention to your comp.
