A
computer virus is a program written with a purpose to destroy another
computer, or to access it’s files, usually without the computer
user's knowledge that it is there. The virus attaches itself to a file or
directory, where it creates a clone of itself, and then continues to
spread through the system. These viruses can cause severe damage, which
may lead to removing all data on the computer’s Hard Disk or Drive.
Computer viruses, can only be transferred by sending an infected file
to another user, over the Internet. Another way, is by saving an
infected file onto a disk, and opening the file on another computer.
This is why there is a need for Anti-virus software for our personal
computers.
Computer viruses can spread from computer
to computer from being effected from a Floppy Disk, exchange a program,
use of illegal software, download of suspicious files and retrieval of an
email or even a network server. These viruses will continue to destroy
PC's until they are stopped, cleaned or until the computer is completely
infected
By installing an Antivirus Program onto
your PC, and completing a scan of your computer monthly will decrease the
chances of being infected by the virus again. The most famous
anti-virus softwares are
Norton Anti-virus
, Mcafee
and Dr.Solomon
Please note that these softwares are to
be updated regularly to beat the new viruses.
Before opening any attachment which has
come with your email is to be checked for virus before opening. It is not
advisable to open any suspicious messages.
