>Please note the double-extension in this worm. Configure your Windows to show all extensions - a double extension (like MyConfidencialDocument.DOC.EXE) indicates a very high probability of virus infection.
In other words, if you hide extensions (unfortunately the default in Windows), you will see MyConfidentialDocument.DOC.EXE as MyConfidentialDocument.DOC, and think it is only a Word document. Many worms take advantage of this fact. (Of course I am aware that a Word Document can carry a virus, too.)
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
