Very nice. The only thing I would bicker about it turning off system restore before running the tools. Especially as you have the theoretical "idiot" running several different tools including HijackThis & regcleaners. It's easy to make a mistake with those tools if you don't know what you're doing. If someone was to follow your instructions and then do something ignorant and hose their system then they have no system restore left to fall back on.

As I understand it, nothing within system restore can infect the users computer. And everything in system restore is gone when you flush your restore points. There is no need to turn off restore and then run your cleaning apps. Simply disabling and re-enabling system restore after a thorough cleaning is enough to accomplish this.

Other than that, I think it's a nice tutorial that explains the basics on a simple level. Good job!
