As much as I admire your desire to learn to code, I would personally say thats the entirely wrong way to go about....you would be better off with a pocket reference (I suggest O'Reilly personally) or an actual lesson by lesson book if your determined enough.
That is a tinker toy for toddlers, no offense.
One thing I gotta add though, your never going to be able to learn enough to just be aware of malicious code...its either you really learn or your wasting your time.
There is no halfway, being able to see without being able to code...and in all reality, its a lifestyle to some and work for most others, but its something you never stop learning...its practically endless. The lower the code you learn, the easier the rest is to understand, but even if you were to master the base languages and do anything with that, it still means you have to reinvent the wheel to do some of it....or learn a higher language.
Its practically impossible to learn every aspect of it in every language, but the more you understand how the basics work, the easier all the rest becomes.
Its like learning Latin, it will make learning alot of languages a much easier task, but some languages don't actually come from latin and all the changes are still going to take time and effort to learn.
