Receiving alert regarding accessing this website, though host dns is the same

Hi experts,
I have been receiving an alert message “Warning! Accessing this website is not allowed. ” though like VM, my host DNS is the same. After getting this warning, I have changed my DNS server on the VM to different servers, but still, I am getting the warning.
Presently my PC is running with Windows and Norton DNS.
Windows XP (I have tried altering DNS server to a dissimilar ones but received the same warning)
Alert from Norton DNS on VM:
Anyone have idea regarding this issue. Please help.
Thanks in advance.
