MICROSOFT
AND VIRUSES
There
are two types of viruses that usually get into Microsoft products. They are as
below, in no specific order.
1.
Macro viruses
2. Email viruses
The
email viruses are a lot more dangerous to most users than the macro viruses.
The reason is the email viruses can cause you to lose data and, if you're
using a Microsoft email program (Microsoft Outlook or Outlook Express), the
viruses send themselves, without your knowledge, to everyone in your address
book. Some of the newer ones send to each person whose email
is in your Inbox.
MACRO
VIRUSES
Macro
viruses affect only the applications that the macro is written in, and thus
don't affect your entire hard drive; you don't lose all your data or have to
format your hard drive. One of the best methods to avoid getting
these type of viruses is this: when you open a document, unless
you recall placing a macro in it, when the application asks you if you
wish to open the macro, say no. By doing that, the macro won't open and
damage the document. These types of viruses will damage (corrupt) the
document you're working on and sometimes spread to other documents in the same
application. It won't cause you to format your hard drive. Macro
viruses are written in the MACRO LANGUAGE of the applications that the program
uses. A macro virus made to affect Word documents won't damage
(corrupt) an Excel document. To learn more about macro viruses in
general go to these URL's:

One
of the first macro viruses was the Laroux virus and there are many variations
of this virus. To learn more about this virus go to any of
the following URLs. There are many variations of this virus and we are giving
you a few to read up on.

EMAIL VIRUSES
Most
of today's viruses are sent by email, without the person sending the virus
knowing they sent the virus to someone. These viruses go
through WINDOWS MAPI system. There are hoaxes that state by putting
in a false address beginning with !!! the virus would be stopped.
This isn't true at all. If it was email you sent, it would stop the
email from going. Because it was programmed to send by
itself, it sends itself to all valid email addresses in your address book and
many to addresses in your INBOX. As an example of these
viruses sending themselves: a couple of years ago someone I was
associated with sent me an email with the subject " I Love you."
I knew this person would never send me such an email, as we only emailed
each other business things. What I'm trying to to tell you is this:
that by looking at the subject you may know it is a virus and delete it
before your computer gets infected and you send the virus to more people.
What you should do as soon as you determine that a person sent you a virus-
you should phone them (provided it is a local call and you have their phone
number) and inform them they have such and such a virus. If you
can't phone them, email them and inform them. What I did in the case
above, was call the person by phone with the information. The person
thanked me for the information and asked for removal details.
No one would become angry at being told they have a virus, as
no one would want to keep a virus on their computer, and send it without stop
to family and friends. One way, and the way I most highly recommend, to
avoid getting an email virus is by not opening any attachments that you
weren't informed you would be receiving, and also by verifying the size
of the attachment. If the file is bigger than you are
expecting, it usually means there is a virus in the file. Viruses
do make things bigger as they are coded into things.
WHY
ARE MICROSOFT PRODUCTS TARGETED?
As
you all must be aware, Microsoft is one of the biggest software vendors in the
world, thus people target them to get attention. If they
targeted John Smith's software, whom no one had heard of, would it make
the news? I don't think so. Thus, by targeting Microsoft, they get
their name or virus they wrote in the news. Of course Microsoft is doing all
it can to prevent these holes for viruses to slip through. They
have hundreds if not thousands of software engineers looking into ways to make
their products more secure to avoid viruses going through them or allowing
someone to hack into your computer. Also, Microsoft themselves, had to
close down their servers on occasions due to getting one the viruses that went
through a hole in a Microsoft product. They lost millions of dollars in
revenue, plus paid employees overtime to remove the virus from their servers, and
had staff who couldn't work but still had to be paid. So a
virus is not something Microsoft wants at all. Microsoft finds out sometimes
about the holes from security companies before or right after a virus is
discovered and starts working to make a patch to correct that problem. At
Microsoft's web site you will see many patches to correct various problems
(either security wise or user problems) that had to be corrected. One of the
viruses that got into Microsoft's server was the "I Love You" and, if
my memory is correct, they had to close their server for two days to remove
the viruses and get everything set back up correctly. Although a
lot of viruses do go through Microsoft products, let's not constantly criticize
them. They are doing the best they can to avoid having holes
to let viruses slip in.
We also have a part to play by being careful
what attachments we open and, if we do unknowingly send a virus, notifying
the people receiving it, so they can delete that message in
order that the virus won't spread. Also, if you spot a hole,
inform Microsoft so they can plug the hole before someone else makes a
virus that will slip through.
FLASH!
Rash of new
viruses
As
many of you must be aware, in the past couple of weeks there seems to be a rash
of new computer viruses. I say there isn't really a bigger number of new viruses
coming out then is the norm. On the average day there are at least 10 new viruses
coming out. For more details on this, go to this URL:
2001:
Year of the Virus
What
you should do, and I advise each and every one of my clients to do is, at least
once a week, is update your AV data files. If there is a real major outbreak the
new data file protecting against that particular virus will be made usually the
same day. Most AV vendors update the data files on Thursday PM's so go after 8PM
EDT to get the new data file and protect yourself.
