What is a computer virus?
A computer virus is simply a set of computer code that
is written by some unscrupulous person. This code is
attached to parts of the normal computer operating
system or computer program. Instructions in this code
tell the computer to perform some task. This task is
often a destructive one, such as deleting important
information or crashing the hard disk.

How Does a Computer Get a
Virus?
Computer virus is passed from
computer to computer either through the internet or file
sharing. A virus can be attached to any file that you copy
to your computer. If you download files from the Internet or
copy programs or files from friends, you are very
susceptible to viruses.
Many viruses are spread
through e-mail. Certain types of today's viruses are
different. They are very dangerous because you do not even
have to open an e-mail attachment to release the virus.
Opening the e-mail itself can release dangerous bugs.
A worm is a program that
duplicates itself over a computer network and usually
performs malicious actions, such as using up the computer's
resources and possibly shutting the system down
A Trojan is a program that
may appear to be legitimate, but in fact does something
malicious. Trojans are often used to gain backdoor access to
a user's system. Trojans do not replicate as viruses do, nor
make copies of themselves as worms do.
How do I know if my computer
has a virus?
Activation of viruses can be
almost anything. Virus can be activated the minute it is
installed. It may initiate its dirty work the next time you
start your computer. A virus resides inside your computer in
an inactive state, waiting for a certain event to happen.
You can have a virus in your computer system and not even
know it. A virus can wait patiently in your system and
attack only on a certain date. Of course, in the time
between the moment you contracted the virus and the time it
made itself known to you, you may have innocently spread the
virus to others. The most suitable way to detect is to scan
your computer with a up to date antivirus program.
How do viruses infect
computers?
Your computer can get a virus by downloading an infected
file from the Internet, file sharing, Infected boot disk,
