Hello.. I was posted 10 Easy Ways Speed Up Computer yesterday. And now, i will sharing about How Viruses Work Contaminate Your Computer. Many people dont know how viruses contaminate the computer. But in here, i want explaine that.
Viruses
are little bits of software that normally have a negative impact on our
computers when they are activated. Usually viruses are attached onto
other software programs (games, disk utilities, office documents/Macros,
screen-savers), and are activated when these normally harmless programs
are started.
A
virus is inactive until the infected program is run or an infected boot
record on a floppy/CD is read. When the virus is activated it loads
into your computer's memory where it can perform its nasty job or spread
itself to other programs on your system or computers in your network.
Floppy
disks used in an infected system (or CD-Roms/DVDs burned on an infected
system) can then carry the virus to another machine. Programs
downloaded from USENET, or file-sharing programs (Kazaa, Morpheus,
Limewire etc.) can also spread a virus. More frequently now, email is
also becoming a favourite way to spread viruses, Trojan horses and
especially internet worms.
It
should be made clear, that USENET and file-sharing programs do not
create viruses or infected files in any way. It is certain anti-social
people who create viruses, and then use these services to spread the
infected files to other users on the system.
This
is very similar to cars and highways in that Ford, Toyota or the
highway makers do not cause traffic accidents, it is the idiot who got
drunk and then drove who causes a 14 car pileup. Of course if there
weren't cars or highways there wouldn't be an accident... then again,
the idiot would still be getting smashed and driving his horse-carriage
into the store window.
When
you get a virus on your computer, it can erase everything that you have
on your hard drive. Each virus is different - some of them come up as
strange messages on your screen, while others just work at eroding the
files on the computer. A virus just doesn't appear in your computer -
you have to put them there, usually by running program from the Internet
that contain viruses. They sometimes come from attachments in emails.
It is possible that an email from a friend could contain a virus if that
person's computer is infected. With anti-virus software installed on
your computer, this will tell you whether or not it is safe to open the
email with a message such as "No virus detected in incoming mail:
