Ugh! I did not want to spend the last 6 hours of my day like this!

So, I recently got an NES Classic with my Christmas money. Being bored, I chose to hack it. (No way am I satisfied with just the 30 games on it.) The software you need to get to do so causes zero harm to your computer. It's the roms where you have to be careful. Go to the wrong place and you can end up like I did.
So, let it be known, do not go to Free Roms if you are doing that. You could end up downloading malware that causes multiple problems. I tried to run my multiple malware killers, but then the thing attacked with malware that restarted the system and locked me out.
I tried my password and it didn't work. I downloaded software to get around that. Found that my password was forzen and that a new administration was keeping me out. So, with little other choice, I reformatted my computer. I'm sure I haven't even downloaded everything I need to yet.
Yeah, did not want to spend my day this way. Especially my day off of work.
