You may want to add hosts to the spybot's list of baddies using notepad..... That way you can import your hosts list to their ofline "includes" update, S&D's host list is stored in in "hosts.sbs" import your list into there; using their format; before running the includes update. On a side note; If the above isn't something that you want to do. I found a good practice that recommends replacing the hosts file all together; delete the hosts file from windows folder; replace it with the original from your windows install CD, or system restore cd i386\hosts\ then instert the mvps hosts list into the newly replaced hosts file on your local drive.. Then "add" S&D's list to your hosts file via the S&D's tool. If it continues to replace your hosts file, try my first recommendation..
