They're all part of the solution. There's a download link on the page for each step. Then, if you ever get an infection, you can just open and and run the programs. (If a paid edition of any of any is also available, the free edition is adequate.) It's best to be prepared: some infections prevent you from downloading or installing new software; plus, the longer malware stays on your computer, the more it might spread and do damage.
