The original Confiker checked around 250 different URLs every day, looking for updates.

The latest version, however, will be an awful lot harder to track and stop.

The newest edition of Confiker, also known as Kido, Downadup.C and Conficker.C, causes infected machines to search a much larger list of domains, believed to exceed 50,000 in number.

Confiker first came to prominence back in November last year and is believed to have infected over 11 million computers already.

    See Stats are back; and we’re blocking Conficker.

    Of course, it may take some time before the domain is listed a malicious, but at least it can stop many requests…
