Types
of Infection
There are many different type of Viruses that can infect
modern computer systems. The most common types are:
Viruses
A virus is a small piece of software that piggybacks on
real programs. For example, a virus might attach itself
to a program such as a spreadsheet program. Each time the
spreadsheet program runs, the virus runs, too, and it has
the chance to reproduce by attaching to other programs.
E-mail viruses
An e-mail virus moves around in e-mail messages, and usually
replicates itself by automatically mailing itself to dozens
of people in the victim's e-mail address book.
Many new viruses send e-mails out showing your e-mail address
in the From Field. It may have obtained that address from
someone’s e-mail address book or other file that contains
a list of e-mail address. The infected computer attempts
to send to any e-mail address that it can find, and if it
is not a valid address the receiving e-mail servers Mailer
Daemon will respond letting whatever address is in the From
Field know that they are trying to send to a bad address.
Make sure you do keep your Anti-Virus programs definitions
up to date; there are new viruses out every day. |
Worms
A worm is a small piece of software that uses computer networks
and security holes to replicate itself. A copy of the worm scans
the network for another machine that has a specific security hole.
It copies itself to the new machine using the security hole, and
then starts replicating from there, as well.
Trojan horses
A Trojan horse is simply a computer program. The program claims
to do one thing (it may claim to be a game) but instead does damage
when you run it.
Protecting Yourself
There are several things that you should do to protect your computer
from infection.
Antivirus Software
This is basically the immune system for your computer, without
updated Anti-virus software a virus can wreak havoc unchecked
and unnoticed.
Not only do you need anti-virus software, but it needs to have
it's virus definitions kept up to date. There are new viruses
every day! Most virus scanners can be set to update automatically.
