out of the blue avast popped up saying my device was not secure. Its not saying wifi router, its saying my macbook pro.
I checked my router anyway. Its clean. Static DNS servers configured (those supplied by my ISP and I have been using for 10 years).
If I look on my mac, which it says where the problem is, I see the DNS servers are 8.8.8.8 and 8.8.4.4 (because I hard coded them as this, it doesnt get them from my DHCP serving router).
So what is the hijack, and how do I fix?
