You really cant trust anything on the other side of your firewall. I am committed to blocking ads as much as I can but it's really just whack-a-mole, for every one you block there are ten more new sources worming their way into your network. I'd love to just go to a whitelist method of blocking, but the bosses get up in arms when they cruise the internet on their lunch breaks (yeah, it only happens on lunch breaks....nudge-nudge, wink-wink).

Surely there must be something similar for Windows.
