The email will arrive with the following characteristics:

Subject: (The subject of the email varies).

Attachment: (The attachment has a random file name).

Body Message:

I'm sorry to do so,but it's helpless to say sorry.

I want a good job,I must support my parents.

Now you have seen my technical capabilities.

How much my year-salary now? NO more than $5,500.

What do you think of this fact?

Don't call my names,I have no hostility.

Can you help me?

This message may not be visible on older e-mail programs that are not able to display HTML messages.

The current versions of most anti-virus programs can detect and remove this virus, so be sure to update if you have not done so in the last couple of weeks.

Users of Outlook and Outlook Express should consider turning off the 'preview pane' so that this new generation of worm/virus code can not auto launch when you click on a message.

To turn off the preview pane in Outlook Express, make sure you are in your Inbox then click on View/Layout and remove the checkmark from the 'Show preview pane' box.

To turn off the preview pane in Outlook, click on View/Preview Pane.
