Need Help Fixing Wonky Computer After Downloading Fake Torrent

Hi all, was hoping to ask some help here before I posted to the specialist forum. I downloaded a fake torrent and I think I've been having computer problems ever since. I don't think it's an ongoing infection as task manager doesn't show any excessive usage going on, it's more like I got drive-by'd and need help fixing the damage. My computer is just really unstable and will crash at the drop of a hat, so I'm wondering if it might be possible to fix any problems by using the Windows install disk. I'm using Windows 10 and Firefox browser, have scanned with Malwarebytes (found 6 PUP's, quarantined them all). When I downloaded the torrent, when I clicked on it it was a shortcut to command prompt but I couldn't see if it did anything from there. Any help would be most appreciated, thanks.

 

Ok, thank you very much for the reply. Trying to get a new comp for Dad before Win7 stops being supported so need to put some ducks in a row but I'll try and get on the Read and Run ASAP. Thanks again.
