So long story short I left home for a couple hours with my pc left on. It had been on overnight the day before too so it had been on for a while with no issues. After I came back home my pc was on a really low res version of what looked like the interface that is shown when you go to advanced options to boot in safe mode. I tried to just go to windows, I tried to boot in safe mode, I tried to repair my pc, but it would just say “diagnosing pc” and it would send me back to the screen I started on. I reset windows but kept personal files and anything that was on my d drive. I booted windows, and it worked. After redownloading all my files, I ran a quick scan and a custom scan of just my c drive. No viruses were found. I looked in task manager to see if there was any viruses in the background and I found smphost which supposedly is sometimes a hidden virus? I haven’t really had any problems since resetting and redownloading windows. I did see suspicious activity in the past; like my antivirus being turned offline and not being able to turn it back on, which I installed and used my malwarebytes free trial and no viruses were found. Do you think I’m ok now or not? I don’t know too much about viruses so I’m not sure.
