guys this may sound like a stupid question, but what are the contents of you ETC folder on you mac? here's mine:

-Host
-Host.sb-YKhmEe
-imhosts.sam
-Networks
-Protocol
-Services

That hosts.sb looks kinda fishy to me, i feel like it was not there before, just not so sure of it since i cant remember the exact content of the ETC folder, so i decided to ask you guys instead of what are your files inside that folder. Thanks!
