FIX: Evil MSN Search spyware behavior for DNS errors in MSIE
In Microsoft Internet Explorer >= 5, a DNS error (asking for a hostname that doesn’t exist) causes IE to pull an evil stunt and feed the requested URL to http://search.msn.com/dnserror.aspx , where it is used to search MSN and logged for who knows what nefarious purpose. Rather than being opt-in behavior, this is opt-out, and rather than making it clear with a choice in options like “Automatically search when a site is not found”, opting out is a matter of making this choice:
Tools:Internet Options:Advanced:Search from the Address bar:Do not search from the Address bar.
Irksome.
