Hi,
Yes, i tried to restart PC again, and all shileds was (and still are) on. Other think is, that i am not entirely sure, that Web and File System shileds was on, the Behaviour and Anti_ransomware was the only ones that shows up on main screen of Avast after opening it, and i just clicked on fix all, so i wasn't in shileds section, if you know what i mean.
