| 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 apps 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. |
