MAC DNS poisoningLocked
just noticed that my DNS server address values in my Macbook are 184.108.40.206
220.127.116.11. I searched it over google and i found out that it is indeed malicious. i tried to remove it however, it is grayed out and I cannot remove it from the list. i also tried to flush the dnscache. however, it is still the same. do you have any suggestion?
