Im pretty sure i was Hacked off just to get banned and framed

I was playing a few ranked games of league with my bro as on the last one I played (is the match history above) we were in a lobby before that game where a guy was planning on going warwick top with smite. I so thought it was a mistake so I simply said "war you have smite" he responded "muted and reported" after that we had a remake in champ select this time the guy was no where to be found (I am also keeping his name off the chat cause I'm sure I'm not allowed to post it) but as we were starting the game I strangly never got to the loading screen to where I thought I just had to reset my LoL but as the game load ( thie information of what happens inside the game is from my brother as he did load in and from the match history as proof )But my brother said that while he was telling the team that I was coming back the same player from before as warwick was now tryndamere and he made a comment on me not being around i.e. "cho is having fun connecting? lol" since i was cho gath that game. As my brother was telling me what was going on in our skype call and I was about to reset my LoL it popped up that my computer just randomly had gotten suspicious malware/ malicious content just as soon as i was reseting my league. It all happen in such a coincidence that it seems too good to be true so i wanna ask can anyone help me or get it checked out to help me get my lp back or not get demoted or something from riot i think this will only get worse not just for me but for our community as far as we have come to try to make it somewhat better. Thank you for your time reading this
