Have Norton security deluxe installed on a macbook pro and it is saying "your vulnerability protection definitions are not up to-date. Your mac maybe at risk. When the fix icon is clicked on, it doesn't do anything. Have tried many times, even from my Norton account but to no avail. The operating system is macOS Big Sur. Can anyone help and with a fix for this issue.
Thanks in anticipation of any responses.
