I have a 5 year-old mbp 15" 2.2 GHz Intel Core Duo running OSX 10.5.8. I have been using iAntivirus happily for years. I stupidly decided to trial run the MacKeeper 2012 software. When I saw the price after installing and running it, I decided to uninstall it. It will not uninstall. I have tried everything. It remains on my desktop and in my applications. Is there anyway that I can force uninstall on a mbp? Thanks for tips.
