After being told that "the computer isn't working" (and that was it), I went to look at it. It starts up normally, and goes into Windows as usual. From there, things are different. Instead of the background on the desktop coming up, an orange background shows up. No desktop icons show up, but the toolbar at the bottom shows the automatically-running programs going. Then, a message comes up: "Catalyst Control Centre: Host application has stopped working". I went into Windows Explorer to see if I could get my mom's pictures on a flash drive, but only a few folders are available: PerfLogs, Program Files, Program Files x86, Users, and Windows. (Pictures have been put in a new folder.) One thing that was interesting was that I was in Windows Explorer, I could hear an advertisement going on, as if a video ad on espn.com or some place similar was going. I have not tried many programs, but Microsoft Word appears to work.
I should mention that a little while ago, Live Security Platinum showed up on the computer, and based on a tutorial that I was using, I entered a phone registry key that made it think that it was purchased. I then went to follow the other steps, and Malware Bytes Anti-Malware and RKill both dd not find anything. I hadn't gotten any farther than that, due to being busy.
I'll try to find out what happened when things first went bad, but there's some information for now.
