| 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. |
