Help, Groovorio won't uninstall,

Thank you for the help. I have done everything, EXCEPT that the Keybar22 Toolbar. When I clicked on it, and uninstall, I would get the little "working" circle for just a fraction of a second, and then it would go off. I tried several times. Everything else you instructed me to do I was able to do,

I have always used Avast Antivirus, but some way it got changed to Microsoft Security Essentials, which I have never heard of, so I for sure didn't change it. Should I just leave it alone?
