Worm/Klez.E has been the most prevalent virus according to Central Command's tracking for twelve of the previous fifteen monthly Dirty Dozen reports.
"Fortunately, July 2003 saw no new significant virus outbreaks. The only minor noise produced was for the Worm/Gruel family, however, several attempts by the virus author to proliferate its creation proved unsuccessful."
