Crap Killer searches installed programs containing particular keywords, like tuner, toolbar, evaluation and free, and uninstall them automatically.However some keywords as free could uninstall legit softwares too; uninstallation is usually cancellable, but to avoid these problems you can modify the file Crap Killer.cmd with a simple text editor (Notepad too) and delete the line /c:" free".
In this way you can also add new keywords.
