I think I have a virus

Some ****** name turdsamiches from here gave me a link to something a long time ago. I ran it and my screen turned blue and it crashes my PC. Ever since then my PC been super fucking slow, and when my PC starts, it opens 2 CMD prompts. 1 says C:user

user):app data: raoming: explorer.exe.exe
Another one says app data: local : updates.exe
I've had problems with things like I can't right click and access properties, I can't edit settings of some things, can't access internet options etc.
So today I opened the app data roaming folder and found these here:
The bot.exe is what caught my eye so I did some research and found out that botnets make is so you can't do a few things like I was talking about. One of those things is access the website malwarebytes.
I tried to go there and ofc it wouldn't let me. I told my brother to try, and sure enough the website was working for him. I don't know the first thing to do besides system restore, and I have alot of shit on here I don't want to get rid of. If anyone here knows about viruses and thinks any of that sounds familiar, let me know please
