Repeated notifications- Backdoor.adwind activity.

Hi,

I am recieving repeated alerts about the 'Backdoor.Adwind detection- SID: 28846' and a traffic block message for traffic from 185.17.1.241(alert attached). 

Referreing to the below article, I have tried running the Symantec Power Eraser-SymDiag Tool and Norton Power Eraser. However, I am still recieving the alerts twice in one minute. I understand that Symantec is able to detect the malware, but I am trying to find out what is the source of the malware and how to stop the alerts permanently.

Thank you.
