if real site is on or not is not the point.
It sure is as it can make a difference.
as a network administrator what I set for the DNS servers is what should be used.
avast doesn't prevent you from doing so. So what is the problem ?
without warning after installing avast premier all features of internet filtering and domain name redirection are thrown out the window.
So you do not look into things before installing something. Real bad practice for a admin.
original question how do i keep avast from using alternate DNS settings period.
Did you even read the page Pete posted ?
