Hey Andrew,
LOL, yes that can be a better solution when a PC is as infected as yours was. But it's nice to start out clean and fresh.
You would probably do well by reading the article, PCHF Protecting Your PC, to learn all of the things that you can do to protect your computer from being infected.
Hope to see you around the forums, don't forget to recommend us to your friends and family.
TTFN
