Viruses after resetting windows 10 to factory settings?

Hey everyone - I recently upgraded to Windows 10 from 7, and when I did I received a ton of viruses. I assumed these were downloaded previously, And couldn t be run on 7, which is why they were appearing now. I decided to reset my computer to factory settings. Now however, I have the same exact viruses popping up, although I d deleted them. The only things I've downloaded since resetting are Minecraft, Google Chrome, McAfee, Paint.net, and the Minecraft Forge installer.
I looked it up, and none of these are said to contain viruses, so I don't know how they could have gotten on. It's become quite a pain because the virus doesn't allow me to open chrome, it just makes chrome not respond, so I have to use Microsoft Edge.
Anyway, if anyone has any suggestions, they are greatly appreciated!
