BAD VIRUS WARNING - TWO IN ONE
Hi,
I just came across this warning and I wanted to share it. Sincerely, NanceeVirus
~~~~~~~~~~~~~~~
Alert: Klez "Super Worm" (2 viruses in one)
To: Technical Professionals
Klez is a highly sophisticated "superworm" that originates from Hong Kong. There are now two versions of the Klez virus, (as bugs in the 1st version have been corrected to make this a more dangerous threat).
There is significant innovation in this new threat, as Klez is actually 2 viruses in one EXE file. The Klez worm is the mass mailing component that carries another a second highly destructive virus called Elkern within it. Once Elkern is implanted on a PC, it can be highly destructive. The payload is randomly activated during the 13th day of odd numbered months (November for example). If the payload activates, then all data on drives C: thru Z: would be set to ZEROES making this virus highly destructive.
Both versions of this new virus are the 5th and 6th most prevelant viruses in the world. Just copy of this virus could be highly destructive to information residing on our Networks.
Our Lotus Notes environment is already protected to intercept this for Internet EMAIL. Leon's latest update also provides desktop protection. Still, please be careful here and at home in processing any attachments.
Thank you - Harry

Klez + Elkern Information
Steps to Prevent Infection
1. Please continue to delete all EMAIL attachments ending in EXE.
2. If you use Outlook EMAIL at home, DO NOT USE PREVIEW MODE.
3. You can apply a patch for Outlook to prevent automatically launching attachments in PREVIEW mode at http://www.microsoft.com/technet/sec...n/MS01-020.asp
4. It is recommended that you view EMAIL in PLAIN text mode rather than HTML where you have this option.
Message Body: (This text is hidden if you process EMAIL in HTML mode)
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?
