E-Mail
Virus - Mydoom E-mail Worm
Returns
![]()
The
"Mydoom" e-mail worm has returned. First discovered in January 2004,
Mydoom became one of the top ten most prolific virus/worms of last year. Now
anti-virus companies have reported a new variant of this mass-mailing worm. The
variant is called "W32.Mydoom.AX@mm" and its discovery is one more
example of why we encourage all our Internet users to install virus-scanning
software on their computers and to frequently update their security software.
(Note: Mydoom infects only Windows-based operating systems — not Macintosh,
Linux, or UNIX systems.)
The W32.Mydoom.AX@mm e-mail worm (also known as W32/Mydoom.bb@MM) is a
mass-mailing worm that sends itself as an e-mail attachment to e-mail addresses
found within an infected computer. Although the sender's address, the subject
line, and the text within the message of the e-mail can vary greatly (making
detection more difficult), the "from" address is usually spoofed to
show coming from places like "Postmaster," "Mail
Administrator," "The Post Office," "Mail Delivery
Subsystem," "MAILER-DAEMON," or "Bounced mail." The
subject line will commonly say something like "Returned mail: see
transcript for details," "Returned mail: Data format error
delivered," "Message could not be delivered," or "Mail
System Error - Returned Mail." The message body text varies but may say
something like this:
|
|
"Dear user of (your
ISP domain here), |
The message leads users to believe they have received a bounced back e-mail
message notification from their Internet service provider. When opening the
accompanying attachment, however, the recipient's machine becomes infected with
the Mydoom worm. This results in replicated e-mails being automatically
mass-mailed to the e-mail addresses found on the recipient's computer.
The W32.Mydoom.AX@mm worm also includes a "backdoor" feature that
opens TCP port 1034 on the infected machine. This allows hackers to potentially
have remote access and control of the infected computer.
Remember, receiving an e-mail attachment from a trusted friend or a reliable
source may not necessarily mean they were the actual senders of the message and
attachment. We encourage each of our users to install and utilize
virus-scanning software, to update this software on a regular basis, and to
scan all incoming attachments before opening them, even if the attachment shows
coming from a trusted source. The ultimate responsibility of protecting your
computer against worms and viruses lies with you. In addition, many viruses and
worms spread not only via e-mail, but also through the sharing of files when
using floppy disks, zip disks, and networks, as well as when downloading
software. Be sure to scan these files for infections as well.

Ask
The Help Desk - What
Does "OS" Mean?
![]()
Question: I was reading a
computer-related article the other day and it mentioned "OS." I've
heard "OS" mentioned in conversations but I've never known what it
meant. What is it?
Answer: "OS" stands for "Operating System."
It's the system that makes your computer run. There are several popular systems
available on the market. Macintosh OSX (that's "Oh Es Ten"), Windows
in its various flavors from 95, to 98, to XP, and Linux in its various forms.
If you're having trouble with your computer and you are talking to a tech
support person, he/she will usually ask you what OS you are running. Your
answer will most likely be one of the aforementioned systems.

Helpful Tax Information
In March
http://irs.gov/ -
If you are a "do-it-yourselfer" when it comes to filing your federal
income tax return, the IRS lets taxpayers file returns totally free this year
without the prerequisite of purchasing special software. Already over 60
million 2004 tax returns have been "e-filed." Not only is this method
fast, but also if you owe money you can authorize electronic funds withdrawn
from your checking account, savings account, or even use a credit card. There's
also a link to "Forms and Publications" that'll allow you to print
off and file returns via snail mail.

There's also no better website that covers the sport than the official site for

links to information on Final Four individual and team records (i.e. Bill
Bradley still holds the single game tournament record with 58 points in 1963 while
Lorri Bauman from Drake University set the record in 1982 on the women's side
with 50 points), championship video archives, the brackets and locations for
each of the playoff rounds, articles highlighting recent big games, as well as
ticket price information.
Short
Tutorial - Creating A
Backup Of Your Outlook Express E-mail
![]()
Most people find that both
their personal and business e-mail messages create a kind of journal. In the
same way that people keep shoeboxes of special letters sent from friends or
file cabinet drawers containing letters and documents from business associates,
many users today use their e-mail software as an archive resource.
A hard disk failure or corrupted e-mail files caused by a computer virus could
cause the loss of a user's archived e-mail correspondence. To help safeguard
against such an occurrence, users can create a backup of their e-mail messages.
As the tutorials below detail, a user can copy all of his/her e-mail files,
save them to a secure location, and then restore the files if needed at a later
date.
To backup e-mail messages in Outlook Express 6.0 and Windows XP, follow
these steps:

Macintosh users can protect their e-mail messages and settings by creating a
backup of their Documents folder and saving it to a secure location. Each of
the relevant Microsoft identity files for Entourage is contained within the
Documents folder. It's a matter of simply dragging a copy of the folder to a
disc.
