Beware Harry Potter worm!

Tell any Harry Potter fans at your house not to open any Potter-related attachments in emails from people they don't know. A computer worm that was thought to have been long gone has made a comeback with Harry's help,
ZDNet UK reports . UK software company Sophos reported that "infections by the three-month-old 'P' variant of Netsky have risen dramatically over the past week, thanks to the worm's ability to disguise itself as a Harry Potter game or book." The latest Harry Potter film opened in Britain earlier this week and opens today in the US.
