For a very long time I've been using the Google DNS. You have choices on this, and OpenDNS is another fine choice.

Hi. I had the DNS Changer malware which I have now got rid of but the rogue DNS servers are still on my machine's system. I rang my ISP to get the DNS servers that they use so I could put them back on my machine. But the bad ones are still there too. After a lot of advice and trawling of internet I'm nearly free of them but something's still not right. I'm so close to sorting this and it's so frustrating that I'm at this last hurdle and it won't work.
Can anyone tell me if the steps I've followed in this process are correct? This is how far I've got:
In Terminal type sudo nano /etc/resolv.conf
Enter password
Delete bad DNS servers
There are 4 lines. The last 2 are the rogue DNS servers added by the malware. The first 2 are my ISP's DNS servers. The cursor is at the beginning of the first line so I have to use the back arrow to scroll down 4 lines to the last number of the last line of rogue server then use the backspace arrow to delete the 2 lines of the bad DNS servers.
Press Control - x to exit
Doing this jumps me straight into a highlighted question: "Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ?" I'm given the highlighted options of yes, no or cancel.
Then press y to save changes
Pressing y for yes jumps me straight into the highlighted line "File Name to Write: /etc/resolve.conf." I cannot come out of this highlighted line. I can only move the cursor along this line to the beginning of " /etc..." This is where the problem starts.I was advised to press y again but that only adds the letter to the line. I pressed Control - O as someone else advised to write out the file but nothing happens - presumably because it's not one of the options below. The only options I have at this point, which are also highlighted with this line are:
Control - G Get Help
Control - T To Files
M-D DOS Format
M-O Mac Format
M-A Append
M-P Prepend
M-B Backup File
Control - C Cancel
So I only get as far as saving the file. It seems to accept the save up to a point but then it wants me to do something else. Add to the name of the file? If I do add to the file name, then press return, it jumps to "File exists, OVERWRITE ?" with the options yes, no or cancel. I don't dare choose any of them in case I spoil it or something. If I try to close nano and exit, I get the "closing this window will terminate the following processes inside it: login, bash, nano."
I can't do anything except to close and terminate because I can't complete the process of deleting the rogue DNS servers.
I hope this all makes sense and would very much appreciate any help.
