@guest - AppGuard triggers DNS callouts to wwwDOTdownloadDOTwindowsupdateDOTcom on my computer. I was convinced it was Windows doing dodgy crap behind the scenes, even though I have Updates set to "never check". It wasn't until I uninstalled just to get my security layers blended properly, which gave me a whole half day without that DNS being called. It returned as soon as I re-installed AppGuard. It wasn't really an issue, since I use Acrylic DNS Proxy to point unwanted stuff to localhost... just annoying. What's ReHIPS like, from a browser perspective? I am looking at using ReHIPS for Firefox.
