I don't know how or when it happened. But what I can only assume to be a nasty case of malware got me last night. I noticed when I was playing games with my friends and I wasn't allowed to launch the game because it thought I had a hacking software up. Then after that it wouldn't let me connect to the game networks at all, let alone the rest of my programs. First when I noticed something was wrong, I ran my AVG, but it found no threats. So to be safe I thought I would try to install malwarebytes, but when I tried, it said that it couldn't be downloaded. I then tried to put RKill and Malwarebytes on a usb so I can move them over to my PC from a different system. But whenever I tried I got an error saying that I was unable to transfer the programs. After that I learned that something is causing my C: drive to unwrittable and unreadable. I have no idea what I need to do to fix this.
