Unable to uninstall GeekBuddy

I’ve uninstalled GeekBuddy several times, but every time I do, my computer won’t start normally and the only way to get it to work is to restore the system to a version that includes GeekBuddy. I’m no longer interested in using GeekBuddy and it’s become nothing more than a nuisance now. Has anyone else had this issue?

To Uninstall GeekBuddy

Go to Start > Run > appwiz.cpl > Comodo GeekBuddy
