help! mysterious dns numbers and search domain

[Marta]

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
195.241.77.55
195.241.77.58

Next to that, under Search Domains, "home" appears by itself. I can erase them but as soon as I return they appear again by themselves.

I am worried that that they are malicious and means 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!
