My HP desktop originally cam with Windows 7. I used the free upgrade to Windows 10 and have had issues ever since. I must have downloaded adware/viruses and my anti virus seems to find PUPs and quarantines but it always keeps coming back. I tried using adwcleaner, spy bot, and Mal ware bytes and it always comes back so I am clearly not doing something right. I have tried to restore factory settings to wipe out EVERYTHING and take it back to Windows 7 but it keeps saying no changes made, there was a problem. I've messed with this for so long, I'm not even thinking clearly and this is probably an easy fix but I cannot figure it out. Please help.
