ProctorU uses a Chrome/Firefox extension and a remote software called LogMeInRescue.
To uninstall LogMeInRescue
Once the chatbox is closed, we no longer have remote access and the download should remove itself automatically. In order for us to remote into your computer at a later time, you would need to download LogMeInRescue again.
To uninstall the extension
Right-click the extension or add-on and click remove
