Excuse me, Evelyn, but I thought Smiley Central was something people spent time UNinstalling from their computers, not trying to install it! It usually installs itself without permission in the first place. I had to use system restore to get rid of it after it installed itself uninvited on my PC yesterday.
Do a Google search for Smiley and you won't find many people with positive things to say about it.
Unless you like invasive spyware, that is.
