Virus and Anti Virus issues

Computer Virus
A computer virus is a small hidden program on a floppy disk or a hard disk. Just like a biological virus a computer virus can spread from computer to computer through an infected floppy disk or a computer network and computer programs, files and computer hard wire itself.
How do virus spread?
You can get a virus only by downloading or receiving a file , which is infected that you run on your computer.The different ways in which this can happen are mentioned below.
  1. If you get an email with a file attached to it (an executable program such as .exe or .com ) that contains a virus and you download that file and run it, your computer will become infected . 
  2. If you download a file from the internet that contains a virus and you run it, your computer will become infected.
  3. Virus are also transmitted by computer networks and by infected disks.Do not use someone Else's floppy without first checking it for virus.
  4. If you boot a computer with an infected floppy (boot virus) your computer will be infected.
