W32.Sircam.Worm

This new worm is spreading by email with unprecedented speed; I've gotten it sent to me by *hundreds* of readers so far, most of whom have no idea their PC is spewing out copies of the worm.

It's a bad one: First, it's clever, and actually uses its own mini mail server to propagate itself. But second--- and unlike the vast majority of worms--- this one really can cost you *all* your data!

The worm/virus arrives as an email attachment. The email (which has several variants in English and Spanish) usually says something like:

Other variants include "I hope you can help me with this file that I send" or "I hope you like the file that I sendo you" or "This is the file with the information that you ask for."

The subject line of the email is random, but is the same as the file name of the attachment in the email, which also is randomly generated.

Good news: Nothing will happen unless you actually run the malicious attachment: Don't click on it, and you're OK.

Also, ZoneAlarm correctly identifies and disables the attachment before it can do anything.

And all the major antivirus vendors are on top of this. For example, see:

or

Again, this is an unusually aggressive, clever, and destructive worm. Be careful!
