Intrusion threats?

Yesterday I updated Norton to v22.5.2.15 after 21.7etc broke after doing a system restore (used NRNR tool). I did LiveUpdate until none were found, but then today I looked at the computer and there were 2 intrusion threats in the performance tab. When I click more info, nothing appears in the history at all. Could this be a false positive? I heard it happens with 22.5. Am I getting all anxious for nothing?
