xFinity Advanced Security - Threat requiring action

Hello, 

Got alert that I had 4 attempts of suspicious IP's targeting a specific device in my network.

Followed the instructions on xFinit on how to fix it -  restart, update, etc... but only 3 of the threats went away.  The dashboard keeps indicating that 1 threat needs attention and I am sent again into the endless circle of repeating the actions before and not getting rid of the alert.  Does it mean my device is compromised and should be quarrantined?  Otherwise how to make sure all threats are removed?  Thanks
