I've got a new Vista machine with a new firewall.  I am constantly being interrupted to ok the program Windows Search Filter Host request to connect to the web.  Spybot does not find this program to be a problem, but I want to know what any program on my computer is doing trying to connect to the internet 3 or 4 times a minute when I am not doing any searching or any other thing that would require a search and certainly nothing that requires connection to the internet.  It's reporting something to someone, I just don't know what and to whom.  Any ideas, folks?
