I wrote a lot because I was trying to be thorough but it is quite long. My main problem is after the ---------------------------------------------------------.

 

I have Windows 8.1.

 

A few hours ago I was trying to download an obscure, but trusted exe file but the site that hosted it was down permanently. So I searched online, found one with the same name on a sketchy website, downloaded, and ran the file like an idiot. Nothing noticeable happens so it's pretty obvious that I got a virus. I'm kind of disheartened that BitDefender didn't seem to notice it at all, but oh well. I restarted my computer in the meantime and when I logged in to Windows, the screen was black but my cursor was there. I could open task manager, and all other programs fine. I restarted again and everything was fine. I ran scans on my MalwareBytes but the only things it found in the scan was Lenovo Browser Guard, which it really insists that I delete.

 

What BitDefender did do is block the ad-spam that this thing continuously tried to shove on my monitor. Happens around every 2 - 3 minutes. I looked at taskmanager and found these really shady looking processes on there that were using up some memory. They were called Winrule.exe and privoxy.exe and NSSM, which seems to be a trusted program except it was downloaded without my consent. I opened the file locations and ended the processes, which brought my disk usage down from 100% to 2%. They led me to two folders called Host Service in my AppData/Local folders and a WinRule folder that the thing created in the same location I believe. There was an uninstall.exe in the Winrule folder so I checked my Programs and Features to find this Window Rule Manager(it was Windows without the 's' so this was some novice disguising work going on here) in there. I tried it and it asked me in some broken English why I wanted to remove the program. I tried uninstalling and it actually removed the Windows Rule folder and its contents, although I'm skeptical as to whether it actually just moved them elsewhere or something malicious like that.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I just deleted the 'Host Service' folder and all of its contents and restarted my computer to see if everything was fine. The screen was black again with a functioning cursor, but about five minutes later the screen blinked and my desktop came to normal. Then a popup came up from Windows Script Host that said "Can not find script file "C:\Users\<my name>\AppData\Local\Host Service\launchall.js". "

 

So although I deleted all the files, I think there's still some kind of script in my computer that tries to automatically run the launchall.js in that virus folder that would run all those malware programs upon computer startup? And I think the black screen is a byproduct of it.

 

Picture of the Windows Script Host pop-up: https://gyazo.com/5409818e19cb525208de2e218c341b0c

 

My antivirus programs that I mentioned earlier aren't picking up anything but it doesn't seem that there are anymore ad pop-ups. I don't know how to get rid of this script thing either.
