Help! My young grandson, thinking my IMac was a bit slow, started downloading Mackeeper then found he needed money to continue! Fortunately, whilst I'd allowed him onto my machine he doesn't have access to my cards. I've removed the download as far as I can but cannot shift the Mackeeper icon off the Launchpad, which makes me suspect there is still download programme lurking in my hard drive. Being a "geriatric" I'm not a fluent computer/IT user and would welcome simple, non technical language, advice on how to get rid of this dammed programme. many thanks.
