I have a computer in my classroom that is not connected to the internet, but now has the klez worm. I suspect that some kids inserted a floppy that may have brought it; I don't really know. But anyway, "fixklez" won't work because I always get an "illegal operation" message followed by a message that I cannot have access, and that I need to "speak to the system administrator" or something like that. I suspect that this is as a result of the klez's anti-anti-virus functions. Any ideas? it is not doing anything serious, but it won't go away, and of course removing the KAK.HTA entries in either startup or the registry won't work; it always comes back.
