"Script viruses dominate the list of most commonly reported malware, indicating that companies should consider disabling Windows Scripting Host and blocking VBS files at the email gateway," said Graham Cluley, senior technology consultant for Sophos Anti-Virus. "Top of the pops is the Life Stages worm written by Zulu, a prolific virus writer from Argentina."
