COMPUTER VIRUS

What are computer viruses?

Viruses are small programs that hide themselves on your disks (both diskettes and your hard disk).

Unless you use virus detection software the first time that you know that you have a virus is when it activates.

Different viruses are activated in different ways.

How do viruses infect PCs?

Viruses hide on a disk and when you access the disk (either a diskette or another hard disk over a network) the virus program will start and infect your computer.

The worst thing about a computer virus is that they can spread from one computer to another, either via use of infected floppy disk, or over a computer network, including the Internet.

How to prevent virus damage?

·        There are a number of third party antivirus products available.

·        Most of these are better than the rather rudimentary products available within

·        DOS and Windows, but of course you do have to pay for them!

·        The main thing about your virus checker is that it should be kept up to date.

·        Many companies supply updated disks on a regular basis or allow you to receive updates through an electronic, on-line bulletin board.
