I've heard that computers can be hijacked and be made to send out
spam:  can this also happen to hotmail?

I recently received the following email message in my Hotmail inbox:

"This is an informative message sent by Kerio MailServer 6.0.10 at

Your mail message did not pass the server content filter:

From: <>
To: <somebodyelse'>
Subject: Re: Bad Request
Date: Mon, 8 Aug 2005 14:26:58 -0800

Problem: Virus found
MIME type: application/octet-stream
File name:
Virus name: W32/Netsky.p@MM!zip
Antivirus: McAfee Scanning Engine (4552/4.4.00)

All invalid attachments of the message were deleted and the message was
delivered to the recipient."

The only text I have changed is my email, and the email of the person
who supposedly sent the virus.  The email says it was from, which I don't think is the Hotmail

The thing is, I never sent an email to any address remotely like that,
much less a virus-laden one!  I'm innocent!

And I somehow doubt that this email is in itself a sort of spam or
phishing, since there's no URL to go to, or product to buy.

So why did I receive it if it's false?

Anyhow, 15 bucks if you can tell me what's going on.

Hi gnossie-ga,
    Rest assured that neither your computer nor your hotmail account
have been hijacked. The virus laden email was sent from a computer
that had been infected by the Netsky worm. This worm scans the hard
disk of the infected computer looking for email addresses, and then
mails itself to these addresses using a spoofed 'From' field for these
emails. The From field is usually filled with one of the email
addresses it found on the disk.
    So, the most likely scenario is that the worm infected the system
of someone who had your hotmail address on disk. It then proceeded to
email itself to the addresses it found, using random addresses in the
'From:' field. As it happened,  the server received
the mail which had your hotmail address in the From field, and
automatically notified you.
    More information on this worm can be found here:
        - W32.Netsky.P@mm
    In case you want to scan your system for this worm, you can use
the removal tool found here:
        - W32.Netsky@mm Removal Tool

  I myself had a run in with this worm last year when I suddenly
started receiving around 4-5 virus notification emails from a local
business here. Since I had never mailed anyone in that company, I was
most puzzled. However, a little detective work uncovered that an
acquantaince of mine was working in that company, and had his system
infected by this worm. Now his system was sending these worm laden
emails to his collegues, with my mail id in the from field (!!), and
their updated antivirus filter was catching these mails and notifying
me. The notifications took around two weeks to subside. :)


Hope this helps. 
If you need any clarifications, just ask!

Fantastic.  Exactly what I wanted to know.  And the news was good,
too!  (At least for me.)
