I'm running a Mac with ios 10.11.6, using Malware bytes, Sophos and Bitdefender. Using a new Comcast (Tehnicolor) gateway/router with Firewall turned on and set to medium.
When I reboot the router and check my network preferences, my DNS server is reset to my router address and my DNS Search domain = utopia.net. Which I'm told is a result of a DNS malware/hijack. I can manually change both to back to Comcast, but on reboot they revert to Utopia. I have run malware & virus tools, but again, they find nothing.
Not much info on it online, but what little is there mostly mentions this in relation to Windows machines. Also, in reading the forums, Comcast seems to say it is not their problem, but a problem with an infected machine inside the firewall. I have alot fo devices on our home network, largely all Mac except for an Xbox.
How much of a worry is this and any suggestions on how I can get this permanently fixed? Any help or suggestions are appreciated.
