SOLVED white empty rectangle in lower right corner of Windows 10 (task bar)

[opalescence]

Hello,
I installed Windows 10 last evening; everything seemed fine...
Today I noticed that, because I clicked on something, a white empty rectangle (with "Address" to the left of it) is located on the bottom right of the task bar. I have not been able to remove it.
Can someone help me ?
Thank you,
Opalescence

If you can, please post a screenshot of that area.

Bottom right of taskbar there is no such icon "Address" in my system tray.

This is how mine looks like........

You showed me a Y!Mail toolbar.
That's not Windows 10 taskbar.

Go back to my 1st reply and look at my screenshot. That is Windows 10 taskbar at bottom right.

Hello David,
Thank you very much for your help. I was able to remove the empty white rectangle to the left of the BitDefender icon on the taskbar.
I hope it will not return.

I have a transparent rectangle on a bottom right corner. Win 10. It starts few days ago, I don't know why. Some programm starts it, but I don't know what programm. Sometimes this rectangle become white and also it has a context-menu.
