I had the same problem.  This toolbar is not program and therefore you CANNOT remove this from the control panel.  It is one of those sneaky ones that you can never delete but you CAN hide it.

Do this:

1. If you have uninstalled Wise Convert, re-install it (trust me - this works)

2.On the top right hand corner of Google Chrome, click on the button which has the orange circle on it. This is the Wise Convert toolbar menu.

3 Click on "Hide Toolbar"

4 Go on to Google Chome settings button

5 On the left hand side menu, click "Extensions"

6 Click to remove Wise Convert from Google Chrome

You must hide the toolbar before you remove it from Google Chrome because if you do not do this, you will have a visable unuseable toolbar staring back at you.

Hope this helps.
