Mac's popularity is rising because numerous number of people are leaving  Windows to the simplistic way, Apple. Many are used to the add/remove program's feature in Windows but in Mac, to uninstall, you simply drag it to the trash. In some ways, I find that it is not enough. Especially on Ant-Viruses and other deep level apps. Lucky,there is an awesome application remover called appcleaner. This application removes all scattered files pertaining to that specific application. Good luck and enjoy it; the Apple way.
