| Q: |
WHAT IS A VIRUS? |
| A: |
A computer virus is a program – a
piece of executable code – that has the unique
ability to replicate. Like biological viruses,
computer viruses can spread quickly and are
often difficult to eradicate. They can attach
themselves to just about any type of file and
are spread as files that are copied and sent
from individual to individual.
In
addition to replication, some computer viruses
share another commonality: a damage routine that
delivers the virus payload. While payloads may
only display messages or images, they can also
destroy files, reformat your hard drive, or
cause other damage. If the virus does not
contain a damage routine, it can cause trouble
by consuming storage space and memory, and
degrading the overall performance of your
computer.
Several years ago most viruses
spread primarily via floppy disk, but the
Internet has introduced new virus distribution
mechanisms. With email now used as an essential
business communication tool, viruses are
spreading faster than ever. Viruses attached to
email messages can infect an entire enterprise
in a matter of minutes, costing companies
millions of dollars annually in lost
productivity and clean-up
expenses.
Viruses won't go away anytime soon:
More than 60,000 have been identified,
and 400 new ones are created
every month, according to the
International Computer Security
Association (ICSA). With numbers
like this, it's safe to say
that most organizations will
regularly encounter virus outbreaks.
No one who uses computers is
immune to viruses. |

| Q: |
WHAT IS A WORM? |
| A: |
A worm is a computer program that has
the ability to copy itself from machine to
machine. Worms normally move around and infect
other machines through computer networks. Using
a network, a worm can expand from a single copy
incredibly quickly. For example, the Code Red
worm replicated itself over 250,000 times in
approximately nine hours on July 19, 2001. A
worm usually exploits some sort of security hole
in a piece of software or the operating system.
For example, the Slammer worm (which caused
mayhem in January 2003) exploited a hole in
Microsoft's SQL server.
Worms use up
computer time and network bandwidth when they
are replicating, and they often have some sort
of evil intent. A worm called Code Red made huge
headlines in 2001. Experts predicted that this
worm could clog the Internet so effectively that
things would completely grind to a
halt.
The Code Red worm slowed down
Internet traffic when it began
to replicate itself, but not
nearly as badly as predicted.
Each copy of the worm scanned
the Internet for Windows NT
or Windows 2000 servers that
do not have the Microsoft security
patch installed. Each time it
found an unsecured server, the
worm copied itself to that server.
The new copy then scanned for
other servers to infect. Depending
on the number of unsecured servers,
a worm could conceivably create
hundreds of thousands of copies. |

| Q: |
WHAT IS A TROJAN? |
| A: |
A Trojan is a piece of code that
performs unexpected or unauthorized, often
malicious, actions. The main difference between
a Trojan and a virus is the inability to
replicate. Trojans cause damage, unexpected
system behavior, and compromise the security of
systems, but do not replicate. If it replicates,
then it should be classified as a
virus.
A Trojan, coined from Greek
mythology's Trojan horse, typically
comes in good packaging but
has some hidden malicious intent
within its code. When a Trojan
is executed users will likely
experience unwanted system problems
in operation, and sometimes
loss of valuable data. |

| Q: |
HOW DO I KNOW IF I
HAVE A VIRUS? |
| A: |
You must remember that there are very
many things that can go wrong with your computer
and a virus is not always to blame.
The
only way you can know whether or not your
computer is infected is by scanning your machine
with an up to date anti-virus program. |

| Q: |
WHAT IS SPYWARE? |
| A: |
Spyware sneak onto your machine when
you download many file-sharing
services, open infected e-mails,
or click on dubious Internet
pop-up ads. They can manipulate
your system, record your habits,
and steal your passwords and
credit card numbers. Depending
on their degree of aggressiveness,
they can steal your privacy
or even your identity. And they
can be terribly difficult to
remove. |
