This situation can occur when a port scanning attempt on your system is detected or when an application on your computer tries to transmit malicious traffic to another device on the network or exploit a security hole.

You can find the type of threat and the related device IP address in the notification. Click Change handling of this threat to show the following options:

Continue blocking—Blocks detected threat.
