Lesson 1: Have good discretion in the websites you trust

Not all websites that you go to may be safe, since bad guys want to steal or hurt you. Many websites like to give your computer viruses, which would hurt your computer and making it slower than usual. Instead, professional ninjas should ask their parents if the website is safe and free of booby traps. Even with your parents, you still need to be careful to avoid booby traps in websites since they can be hiding under something cool-looking. Also, if you downloaded something from a trustworthy website, and want to download from it again, some websites pretend to be good guys, so you should be careful and make sure its name is the same.
