The email worm Stration is causing delayed delivery of emails for many email users. The worm is spreading through attachments being spammed out and several hundred versions of the worm were spammed out to users during October.

The worm accounts for more than half of all reported malicious code on some days.

The worm sends itself to email addresses found on the infected computer, forges the sender’s email address, uses its own emailing engine, downloads code form the Internet and installs itself in the Registry.

Norman is able to stop this worm. You can read more about the worm in the worm description.
