Do The Media Spread Computer Viruses?
by: Joel Walsh
Summary: Could the mass media hype about computer viruses actually
make the problem worse?
If you believe what you hear in the media, there are an awful lot of
viruses going around. No, I'm not talking about the make-you-sick kind
of virus, though they get plenty of airtime, too. I'm talking about
the kind of virus that enters via your internet connection rather than
your nasal passages.
What the mainstream media often don't tell you--at least, in most radio
and television newscasts and in the crucial headlines and opening paragraphs
of newspaper articles-- is that many of these "viruses" are not viruses
at all.
What Computer Viruses Really Are
The main reason the mainstream media always are in alarm over viruses
is that they tend to call any malicious computer program a virus. In
reality, there are at least eleven distinct types of malicious software,
or malware, commonly affecting computers today. The most common of these
are worms, Trojans, and spyware.
So, what's the difference between computer viruses and the other types
of malware? The difference is that computer viruses are just about the
only ones that regularly shut down computers and cause other obvious
damage. The most common of the other kinds of malware--worms, Trojans,
and spyware--are usually only detectable with a special scan.
The Real Danger of Computer Viruses
If the other types of malware are so unobtrusive that they can only
be detected with a special scan, then what's to worry about? For starters,
these programs are called malicious for a reason: they are designed
to cause some kind of damage, if not to your computer, then to someone
else's.
Worms are most famously used to damage, destroy, or disrupt other computer
networks than the one on which the host computer is located. For instance,
worms have been used by website owners to shut down rival websites by
sending overwhelming numbers of requests to the computer that hosts
that website. Worms have also been used to send out viruses to other
computers, often without infecting the host machine--after all, what
would it benefit the worm to shut down its host computer?
Trojans, in turn, are often used to insert worms and other malware on
your computer, even if the Trojan itself does no damage.
But even if you don't care what happens to anyone else, you should still
be concerned about one kind of malware: spyware, a kind of malware that,
true to its name, collects data from your computer and sends it back
to a remote host.
Most spyware is only interested in monitoring your internet usage so
it can tell other programs, called adware, what advertising to popup
on your computer. However, there are criminal spyware programs that
steal financial data, or perform a thorough identity theft. Don't think
you have personal or financial data on your computer? Some spyware programs
contain a keylogger, which is a program that copies whatever you type,
usually in order to snatch passwords. Even if you keep no financial
information on your computer, if you ever buy anything over the web,
the keylogger would allow its owner to buy stuff using the same information
you typed in to buy stuff yourself.
Why Blame the Media?
Given the danger of all these different types of malware, isn't it a
good thing that the mass media are becoming hysterical about it? And
can't they be forgiven the sloppy reporting of calling Trojans, worms,
spyware, and other malware "viruses"?
No, no, no.
This is a classic case of bad reporting doing more damage than no reporting
at all. In this case, the damage bad reporting has done is to promote
a common myth that goes something like this: "The only malicious software
is a virus. Viruses damage your computer. Therefore, if my computer
is working OK, my computer has no malicious software. I only need to
scan my computer for problems when there is a sign of problems."
Thanks to this myth, many people complacently let their antivirus software
go months out of date, not wanting to be bothered with scheduling an
automatic update. Just as bad, many people don't have any extra software
to combat the other types of malware that may not be covered by antivirus
software.
In fact, it's not uncommon for people who have found malware on their
computers after a scan to say, "but I never had malware on my computer
before!" But how would they have known if they had never scanned!
Until the biggest mainstream media--and especially television--start
educating the public about the need to have their computers automatically
scanned at least daily, the world will continue to have major, drawn-out
problems with malware that could have been wiped out as soon as soon
as the anti-malware software makers discovered it.
And until that day, the mainstream media will have many more opportunities
to run hysterical stories about "viruses," thereby forcing them to sell
more newspapers and broadcast to even larger audiences of people who
suck at the information trough yet somehow never become full.
