virus Possible Trojan Virus, Reducing Disk Size over time

[NoobRage]

Around a month ago during class, I had to research some topics. Because of that, I went to this website, which automatically redirected me to Google Chrome update page, then auto-downloaded somewhat that was caught by my Bitdefender Free. *Don't click* (http://www.nature.com/nature/journal/v544/n7651_supp/full/544S21a.html)

Bitdefender identified it as a trojan and quickly quarantined it. After it restarted my computer, I ran a Malwarebytes Custom Scan with rootkit scanning, which found nothing, so I thought nothing more of this problem. 

However, recently my disk space seems to have been decreasing (or I'm paranoid). I have viewed other threads similar to this and have done all some steps to attempt to fix the problem:

1. boot into safe mode
2. run rkill and a malwarebytes quick scan
3. I even ran adwcleaner and junkware removal tool by Malwarebytes, with adw only finding ask.com.
4. The next step included using RogueKiller, which I haven't downloaded yet. 

I saw on Bleeping Computer a post about removing viruses registry entries, so I used CCleaner (I backed up the changes and in hindsight, I'm not sure if it was a good idea). Additionally, I also have utorrent, which I am unable to uninstall. I tried to uninstall with with control panel and CCleaner, but that didn't work, so I tried to delete it in CCleaner, but it has stayed within %appdata%. 

Specs:

Operating System: Windows 10 Home 64-bit 

CPU: Intel i7-4702H 2.2 GHz Core 

RAM: 8 GB DDR3L SDRAM

Hard Drive: 512 GB Samsung MZMTE512HMHP-00000 (SSD)

If this helps, the last hour of my free space in bytes were:

67 018 055 680
67 017 834 496
67 016 933 376
67 014 840 320
67 014 496 256
67 014 488 064
67 014 438 912 
67 014 430 720
