Instead of a headline like "Dangerous Fizzer Worm Attacks the Internet," how about "Thousands of Morons Open Obviously Virus-Laden E-mail Attachments"? I kind of like it. It has a light, comedic feel similar to headlines found at The Onion.
I'm running qmailscanner to prevent w32 executable attachments from reaching my users mailbox. This program checks each incoming email based on your ruleset. I set my rules to deny attachments with known excutable file extension, like exe and bat. Some legitimate emails do get denied, but I can live with it.
