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.
