BruteForce blocking

I'm running AVG on one of my computers, and recently getting recurrent AVG popups telling me an incoming connection attempt was blocked. The alert refers to an"SMB: BruteForce."  Not sure how much of a concern it is, so haven't checked the "don't show me again" box. Do I need to be concerned?

Hello Siyabz.
Remote Access Shield allows you to control which IP addresses are allowed to connect remotely to your PC, and blocks all unauthorized connection attempts.
When one or more devices are connected in a same network and exchange files or folders between them might trigger remote access shield to block that attempt to access.
So if the IP address that has been blocked is of a known device, you can allow it or you can be assured since remote access shield has blocked the connection.
