| Occassionally everyone gets a message about a computer virus
that will "...erase everything on your hard drive" or "...render your
computer useless", etc., etc., etc. Well, please DO NOT fall for these HOAX
messages that tell you to "Send this message to everyone you know." Most
messages ARE truely just hoaxes designed by spammers knowing that if everyone forwards
these to all their friends, and to all of their freinds and so on, and so on, etc., the
message will eventually get back to them and "Wah-Lah" they have a complete
listing of email addresses that are current and real. Please DO NOT forward these
messages.
As a rule of thumb:
Viruses are embedded in an "executable" file or command. That is, a file that
ends with "EXE" or "COM". These are called "BINARY" files.
The only other types of files that can contain a virus is a MACRO embedded inside
another file such as a Microsoft Word or Excel file. When opening these files, your
virus protection software will display a message that reads "This file contains
Macros that may or may not contain a virus" Do you want to load the Macros?"
Have you ever heard the expression "JUST SAY 'NO' "? Well, say
"NO" to this one too. The file will still load but without the MACRO. MACROS are
usually just a series of shortcuts that the developer or originator of the file created to
save themselves some key strokes. They do not affect you being able to read the files with
YOUR program.
Most ALL other files DO NOT contain viruses. Why? Because they are opened by programs
that you already have on your computer. Your existing virus detector should already have
cleaned your computer and have a virus protection running in the background. So your
computer SHOULD be clean already. An email message is pure plain old ascii text and has No
embedded programs in it. A simple email message CANNOT contain a virus.
Now lets talk about attachments:
I. Most attachments that are the following:
images or pictures, (.bmp, .gif, .jpg, .tif, etc.)
sound files, (.wav, .au, etc.)
movie files (.avi, mpg, etc.)
webpage address (.htm, html)
These files are opened and viewed with programs already on your
computer. They DO NOT contain viruses.
II. The second type of attachment is the "DATA FILE", such as:
Word Documents (.doc, .wp*, etc.)
Spreadsheets (.xls, .wk1, .wks, etc.)
These are the ones that MAY or MAY NOT contain a macro which CAN
contain a virus but ... the macros CAN be disabled. ONLY ACCEPT
THESE DATA FILE ATTACHMETNS FROM PEOPLE THAT YOU KNOW!!!!
NEVER from a stranger.

One last note for those folks that forward jokes. When you forward a message that has
already been forwarded several times already, you are essentially doing TWO things.
1. You are making the receiver of your forwarded message go through a lot of clicks to
finally get to the meat of the message. Many people get tired of these and may just just
delete them to avoid doing all that damn clicking. Remember, everyone does NOT use
the same email programs. Some are easier to use than others and not everyone is as
computer literate as you are.
2. If you forward all those previously forwarded messages, you are again advertising all
those email addresses that appear in the headings. Spammers love you for this.
(For you computer novices: A "Spammer" is someone who sends out mass
mailings of unsolicited email, i.e., junk mail.
------------------
The best advice I can give is to forward the meat of the message only and not all the
other forwards. It will make your receivers happier.
Just rmember that the most important safeguard against Computer Viruses is, of course,
a good up-to-date virus Protection Program running such as Norton Antivirus. NAV9X.EXE |
