I was so confused on what just happened, that when I got to the first SAVE point in the ruins, I quit the game and went to my group chat. I wrote a message explaining everything that happened. One of my friends (who I will call "Gabriel") using the information I've given, deduced that what I've really downloaded, was a trojan virus. I felt like such an idiot when I read it for the first time. I can't believe that thought never crossed my mind. And what's even weirder, is that downloading it somehow cause everything that I've mentioned last chapter. I started to panic thinking that I was screwed, but Gabriel said that they might have something, but it might wait a while. Me and my friends decide to end the conversation here, and nothing better to do, I continue playing Undertale. To my surprise, nothing really changed. It was just a normal playthrough...sorta. I didn't mention this on the last chapter for the sake of tension, but I named the fallen human "Frisk" because I felt like it, which means I was on hard mode. I assumed that it would end on the Toriel fight like last time I did hard mode, and I would have to reset again, but to my surprise, I did get past the Ruins and on to Snowdin. But before I continue, I should mention that before I fought the Toriel boss started, it moved very quickly, but I think I saw the Annoying Dog being grabbed and drag out of the room by a nightmarish arm. Getting back to the subject, all of Snowdin stay the same, well, except for the enemy bullets being a little hard due to being in hard mode. Even the conversation you have with Sans in Grillby's stays the same, except for one part. I am talking about the part where Sans talks about Flowey, but instead of that, he says this:

Sans: ... something happened. I don't know what it is or what it was, other than it happened. this is supposed to be a warning, but how can I warn you if I don't know what I am even talking about. what I can remember is that it was something awful and terrifying. the fact that I can't recall anything else scares me...but, if I do somehow remember something, I am gonna let you know, pal.

Then once the spotlight turns off, Sans leaves without a word. After that, I had my date with Papyrus, and then ventured into Waterfall. As expected, it was exactly the same, even down to the Undyne boss, but the thing I want to really talk about is Hotland. At first it started out as normal, nothing out of the ordinary, until I enter Alphys's lab. When I did, I saw Chara, with a messed-up creepy face, red glowing dots in their eyes and with a disturbing smile, standing in a black background. Then another message in red appeared:

"DO YOU REALLY THINK IGNORANCE IS BLISS"

Then suddenly, I was in the lab. I walked forward expecting to see Alphys, but was instead greeted by Mettaton. He had this to say:

Mettaton: YOU MUST BE THE HUMAN. WELL, I JUST WANT TO SAY THAT WE CURRENTLY ARE IN A CRISIS. MANY MONSTERS HAVE BEEN REPORTING STRANGE AND CONCERNING THINGS. PEOPLE HEARING VOICES IN THEIR HEADS, PARANOIA, THE FEELING OF BEING TOYED WITH, WITNISSING DISTURBING SIGHTINGS. EVEN SOME CLAIMED THEY SAW THE FIRST FALLEN HUMAN WALKING AROUND. ALPHYS IS CURRENTLY REPORTING THIS TO THE ROYAL GUARD SO THEY CAN START AN INVESTIGATION. PLEASE STAY SAFE DARLING.

Mettaton then leaves the scene. My curiosity got the best of me, so I decided to got to the top floor to see if anything changed, and it did. Instead of the Mew Mew poster, there were seven wooden stakes, with each one having a decaying head of a human child. One of those heads resembled Chara and judging by that, it means that the seven heads are supposed to be the seven humans that came before Frisk. Which is kinda strange since I saw Chara a few moments ago. I went back down and went to the same direction Mettaton did to exit the lab, but before I leafed, I saw a message written in red on the wall that wasn't there before. It has a direction leading to the elevator to the True Lab, and it said this:

"COME IN. THERE IS A SURPRISE WAITING FOR YOU :)"

I reluctantly went in the elevator, and it had the same sequence it had, but when I exited the elevator, something strange happened. I was in a direct pathway with no more split directions. When I walked into the pathway, nothing happened at first. But when I kept walking, a corpse that had the same appearance as Frisk fell from the sky. It scared me, but it seemed to do nothing, so I kept going. The more I walked, the more corpses of Frisk started to show up, even to the point where there were mountings of those corpses. Then suddenly, those same Frisk corpses came to life and started to chase me. I kept moving forward, hoping they would lose me, but they didn't. And when they did get me, I was back at the entrance of the True Lab like none of it ever happened. I took a moment to comprehend all of that, and I did, I decided to continue moving forward.
