I know that you have ticked this as resolved, but I will tell what I do anyway!
I have set vibrant media (and many others) in the host file as being local host - that way, the PC searches for them locally, finds immediately that they are not there and continues on very quickly. Thus, in the hosts file, I have a line
127.0.0.1 www. vibrantmedia. com
And many similar lines which block ads.

Post back if you want more info.
