The Conficker worm is spreading fast, as well as variations thereof. Is anyone not aware that they should be updating their software with the latest security patches by now?
Of interest also is that this worm sells supposed security software which in turn affects the computers. How ironic.
This is using the Trojan horse model of so-called security software that actually does the opposite of the purpose for which you purchased it. I mentioned this as a possible problem with security software in general in a previous post.
