Windows 10: Can a virus stay on my computer after factory reset AND HDD replacement?

I'm not even sure if it was a virus causing my problems, but recently I was having trouble booting my computer, as in, it would take me straight into diagnostic mode and bootrec would say there was no Windows installation on my computer.I figured it was a HDD problem so I replaced it. I haven't had trouble booting since but I've been having extremely slow boot times, and random system files are often unreachable by apps or settings mainly .dll files and also got this random error when opening settings. Error: The Group or resource is not in the correct state to perform the requested operati

Does a FACTORY RESET delete your Virus? Great Computer turns to Crap

Ok, here's my interesting situation. Tried to download a game, then all sorts of spyware, adware, malware and probably viruses started downloading to my computer and taking over the memory. Eventually I started getting BSOD, and because the computer wouldn't stay on long enough to run my malware/virus scans, I was forced to do a FACTORY RESET. I went from WIN 10 to the original WIN 7 that the computer came with. Because I had to do a RESET all my stuff is out of date which is expected.

To make a long story short, what was a perfectly running computer before the attempted game download, now I have a computer that freezes, error codes when trying to install windows updates, and my internet crashes. So my question is, even after a Factory Reset, is the virus removed or do you still have to do a virus scan?

(My attempted AVAST virus scan won't even scan through..it gets stuck at "compatibility check").


Also one more question...if your getting BSOD's...then how can you run win 10 in safe mode as the F8 button is disabled?

 

System reset and viruses

Can a computer virus possibly survive a factory reset? A friend brought over a heavily infected Windows 10 machine. I couldn't get anything to work as far as removing the infections. After performing a factory reset, it was infected about a day later. The virus that keep popping up, is koobface.
