A blog-post over at ZDNet describes how enterprise data-ops can use network scanners to detect and disarm the Conficker Worm vulnerability on Microsoft Windows platforms, before it potentially wakes up on April 1st and begins to disable your anti-virus software.
One wonders whether the ZDNet writer was suffering from subliminal puritanism. The name of the worm is Conficker, not ConfLicker (sic). Presumably, the name is derived from the conjunction of Con, as in confidence trick (to enable it) and ficken, the German F-bomb (when it disables you).
Confession: Aye, 'twas I who corrected the ZDNet scribe. :-)
