I currently get a continuous stream of phishing and fraud attacks, but they are detected and neutralised as they are reported in the log.

Since november 27th, 2016 I get numerous attacks from the adress http:/pliadm.com/ usually bursts of more than a dozen attacks per minute, once 26 during a minute. Ant this usually once a day.
The pc is vaccinated, the protection automatically synchronised from the cloud.
Are there any further precautions to be taken ?
What can pliadm.com be definitely taken out of service ?
