Be advised, there are a host of emails going around warning people of explosions at nuclear reactors in their area. I've received one about an "incident" at Sizewell B that has meant that an area of 100km radius is being evacuated.
If you get one of these emails, just delete it. The link to an information page will attempt to install a new worm on your computer. Apparently the worm is so new that AV software cannot yet find it. Expect that to be rectified within 24 hours. Just be careful for the time being and this time tomorrow run your AV suite updater.
Call me cynical but are those individuals who start these worms etc sick - mentally I mean (if so they can come at stay at my place of work, it's quiet here tonigh could do with some excitement) if not why they only hurt the like's of you and me, with there childish behaviour.
