My computer seemed to be running slow and I was aware I had viruses, I don't have a virus protector and I can't afford one. So I decided to reset my computer without doing a backup. Now I can't update my software or download certain things. Norton comes preinstalled on my computer and it told me that I have a good bit of viruses on my pc. I was just wondering if there was anything I can do to get it back to at least windows 10
