This is rather confusing. I recently had to do a system refresh, but clearly I should have done a system restore. System refresh brought it all back to the state which I bought it in (Acer Win. 8.1), which I clearly should have known..... though I made an impulsive move as my computer didn't start this morning.
Now, given my lack of adequate virus protection installed as I don't have the password on hand to reinstall Norton, I attempted to do sfc/ scannow to make sure nobody/no website installed a virus, trojan, worm, etc., on my computer prior to going to bed. Not that I had any reason to think anyone/anything did but just for extra assurance. Anyways, sfc/ scannow is not working? I am guessing this has something to do with the system refresh, but I'm unsure why? Why would sfc/ scannow not work like that?
