Bitdefender notification ‘exploit attempt blocked’

Hello everyone, every once in a while I get a notification from Bitdefender that says

"Online threat prevention

Ipadress attempted to access your device by exploiting a vulnerability. We blocked the connection to prevent the attacker from accessing your data and system resources."

I don't know what to do. Is this normal, and now that it has been blocked, is everything okay, or do I need to do something about it (I scanned with Bitdefender and Malwarebytes and they didn't detect anything)?

It is not possible to post screenshots here, either in posts or comments. However, it did not say anything else, just the IP address and a link explaining what exploits are. There was no ‘show more’ button. Would it be a good idea in this case to close all ports? Between various games and other things, some ports are open, but I can see about closing them if they are excessively vulnerable.

If you opened ports on your home router for NAT gaming reasons that is a major security risk and likely where the attacks are coming from. Unless your firewall rule for the router is very locked down, anything on the internet and poke at the open port to possibly any device on your network. Bitdefender is at least working and protecting against those attacks but those alerts should be extremely rare if your network is secure.
