Hallo, I have a macbook and when I go to System Preferences > Network > Advanced > DNS, I see a number of DNS Servers I did not add and which return even after I erase them and apply changes. Their numbers are: 192.168.1.254 126.96.36.199 188.8.131.52 Next to that, under Search Domains, "home" appears by itself. I can erase that too but as soon as I re-open System Preferences they all appear again by themselves. I am worried that that they may be malicious and mean my computer has been infected by DNS Changer! Does anyone have information on how I can check if my computer is infected, what it may be, and how I can remove the malware? Thank you very much!
