Norton Antivirus

Hey guys, I’m using a mac, and I use Norton as my antivirus. Sometimes, I get a popup from Norton that says ‘Vulnerability Blocked’. The thing is I don’t know what should I do next, whether to just leave it, or do something about it. Sometimes I’m afraid that there may be a virus in my mac. So can anyone tell me what I should do when the ‘Vulnerability Blocked’ pops up again? And can anyone tell me what it means?
Thanks.
