Not sure how to flush DNS, but it doesnt do it in bootcamp or on any other computers on the network. Tried clearing cache in all the browsers.

Didnt work :/ Still having this problem, doing my head in! On most secured pages. Only been like this since i formatted a couple of weeks ago so i assume somethings missing.
