This is an interesting question.
viruses and worms becoming widespread,they have
gained quite some attention over the past years.
Computer security experts have come up with the
terms computer virus and worms, because they
infect computers and can make them "sick" similar
to how real viruses can make your body sick.
Similar to nature, computer viruses and worms have
a replication mechanism, that means they have the
ability to spread and infect new computers.
virus is a computer program that replicates by
attaching itself to another object. For example,
a virus could be hidden in a Word document. When
you give that Word document to a friend (via disk
or via e-mail) you have spread that virus. If
your friend opens that Word document on her
computer it can then infect other documents, orif
it is a malicious virus might even delete some
A worm is a computer program
that replicates independently by sending itself to
other systems. Thus a worm can spread much
faster. Worms often spread over e-mail. When
worms are received through e-mail, they often look
at the address book and automatically send a
message containing the worm to everybody in that
address book (including your friends). Again, if
that worm is malicious it might delete
Viruses and worms are written by
hackers that want to play around or intentionally
do damage to computers.The best way to prevent
getting infected by a computer virus or worm is to
run virus detection software on your computer.
This will scan for viruses and eliminate them.
Similar to nature, new type of viruses appear all
of the time, so it is important to keep your virus
detection software up-to-date (like getting your
yearly flu shot).
Besides viruses and worms
there are several other annoying computer messages
that can spread quickly. For example, a hoax is a
chain letter that usually spreads a false virus
warning. Jokes can also spread fast. But usually
the don't do as much damage.
