Internet Viruses
An Internet virus is a program or piece of
code that is loaded onto
your computer system and does harmful things against your
wishes. All computer viruses are manmade. A simple virus that
can make a copy of itself over and over again is relatively
easy to produce. Even such a simple virus is dangerous because
it can quickly use all your computer's available memory and
bring your computer to a dead halt. An even more dangerous
type of virus is one capable of transmitting itself across
networks and bypassing security systems.
An Internet virus attaches itself to a
program or file on your computer so it can spread from one
computer to another, leaving infections as it travels. Much
like human viruses, computer viruses can range in severity;
some viruses cause only mildly annoying effects while others
can damage your hardware, software, or files. A virus may
exist on your computer but it cannot infect your computer
unless you run or open the infected program. It is important
to note that a virus cannot be spread without a human action,
(such as running an infected program) to keep it going. People
continue the spread of a computer virus, mostly unknowingly,
by sharing infecting files or sending e-mails with viruses as
attachments in the e-mail.
As a safety precaution, we highly recommend that you have some type of virus protection
installed on your computer before you consider downloading
anything. |
