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.
