Thank you everyone for your help. I'd really like to convince them that there's nothing malicious here (I've been using this site for a long time now, nothing bad has happened), but I'm not sure if they're willing to listen.
My dad is super cautious (he once didn't allow me to download Audacity because someone from his work told him about some Adobe Flash Player virus), and my mom trusts him way more than she trusts me. She keeps telling me that he knows more than online security than me, but his method of avoiding malware is to avoid the internet altogether. They keep treating me like I'm stupid or something. I don't mean to be arrogant or disrespectful or anything (which they'd find all of my posts to be just that), but it's evidently clear that I know more about technology than both of them.
My dad said that the Wii U wouldn't boot the other day and my dad told me that the Homebrew I installed on it was causing it and told me to unistall it. I turned it on and was greeted with a USB error screen. Switched the port, and it worked fine.
If any Homebrew Devs happen to see this, I would really appreciate your input on Wii U malware (or, rather, the lack of it).
