Do you know what a computer virus is? If not, does this cause you fear or hesitation in your day today use of a computer? Or are you more afraid of the technical explanation you would get if you were bold enough to ask? If you read this essay I will attempt to in such a way if you know nothing about computer, you feel more confident just for having read it. Of course the best protection is to understand what it is that we are dealing with so let us start there.It is easiest to think o a computer virus as similar to that a biological virus. A computer virus also needs a host to infect. In this case it infects a program. Microsoft word, Internet Explorer and computer games like solitaire are some examples of programs. They are made up of what is called code. Code is basically instructions telling the program what to do. A computer virus attaches itself to this code and, like a biological virus; its first mission is to infect other programs. What does this happen? Very simply, when the infect program is run, the virus relocates itself into another program. This program in turn may infect another when it is run. I use the word "may" here
To make it worse, macro viruses are platform-independent and so can easily spread between Microsoft, Macintosh and other operating systems. Different type of virus Boot sector virusesBoot sector viruses can infect hard drives and removable media like floppy disks. People readily exchange files in the course of a day's work. Pirated or copied software is always a risk for a virus. Execute only programs of which you are familiar as to their origin. Though not all viruses are written to cause damage to your computer, they exist without your knowledge and so have potential to do so. because, as descried later, this infecting of other programs may only occur after a certain event has taken place. Load only software from original disks or CD's. Symptoms of a boot sector virus may be that your computer gives error messages when it boots, or even worse refuses to boot entirely, or if your drive decrementing utility suddenly reports bad sectors on your disk. WormsA worm is a self-replicating program that doesn't necessarily infect other programs. Purchase a virus program that runs as you boot or work your computer.
