Recently Norton Internet Security 2021 popped up showed Zeroaccess!Inf2 infection warning. It did nothing. It showed me a box that the virus is being quarantine something. I got this popup when I was watching a video on internet. Later on there were no warnings. Again after a few hours when I downloading my emails in outlook I found the same popup on my screen. I think Norton cannot remove this. It just shows me warning. And that too on my emails, which never had happened before. I scanned the system fully, not infection was detected. I am bit worried, that there is some virus in my system which remains undetected by Norton.
