All, I need to clean up a host file from the worm that was out a couple weeks ago. I have done pattern matching but not this big before, can anyone offer some advice on how to clean this up. I do have some machines that have host entries in this file so I don't want to delete any of that information.
Here is the entry that I need to remove: Botzor By cLaSic, Bey UnixIRC Crew greetz to all friends in #ccpower.
