SMB:BruteForce Message

Hi Rob,

We're glad to clarify this for you.
From your description, we see that a device/computer on your network has attempted to communicate with your computer & AVG Remote access shield has blocked it. 
If you're aware of the detected IP address, you can add it to trusted connection in Remote access shield
For further queries, feel free to write back to us.

You're welcome, Rob.

You need to manually check your devices for their Ip addresses & crosscheck if it's the same Ip address that was detected.
To check the Ip address of your computer:

1. Right-click on the Windows logo in the lower-left corner of your screen and select “Settings.” 
2. Click “Network & Internet.”
3. Select “Wi-Fi” or “Ethernet” in the left-hand menu, depending on whether you’re connected wirelessly or via an ethernet cable.
4. Click “Network” in the center column. Your IP address will appear in the next window, in the entry “IPv4 address.”

Let us know if you have further queries.

I am getting the following alert repeatedly. What does this mean? I am running Winodws 10 Pro, small office network. Please advise.

Threat name: SMB:BruteForce
Attacker IP:    fe80::183e:b3c6:1e1:f7d6
Process:        System
Detected by:  Remote AccessShield
Status:           Connection Blocked

Than you for the quick reply. How do I determine which computer on the network corresponds to this IP address: (Ip address redacted)?
