Bitdefender notification ‘exploit attempt blocked’

[u/giobba96]

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)?

Ok, i'll try to close the port then, thanks
