Proxy Issues?

[Miller1113]

So I've had my PC for about a year now and it's not just me using it. Long story short one of my roommates was torrenting some stuff and downloaded some nasty stuff in the process. I couldn't even install MalwareBytes. Luckily I figured out which program was causing the issues, deleted it and all of its files and registries (being careful to not touch the necessary ones), and after this, I was able to install MalwareBytes and ran a full system scan. After quarantining and deleting the files and registries that I missed and the program picked up I was no longer able to connect to the internet. First, Google said that there were proxy issues. After checking my proxy settings and making sure everything was normal, Google said there was purely no internet (Though I was still able to connect to YouTube?). After looking into it on my laptop (What I'm on now) other people had the same issue of MalwareBytes deleting files needed for the internet. I would restore to a previous backup but the most recent backup but the most recent one has the aforementioned virus on it. If someone could help out ASAP this would be absolutely amazing. Having my gaming beast down is kinda giving me withdrawals XD.
